ELECTRICAL SAFETY

WARNING! To reduce risk of electric shock, be certain that it is

connected to a properly grounded receptacle.

1. Protect yourself against electric shocks when working on electrical

equipment. Avoid body contact with grounded surfaces such as pipes,

radiators, cooking stoves and refrigerators. There is an increased

chance of electrical shock if your body is grounded.

2. Do not alter any parts of the tool or accessories. All parts and

accessories are designed with built-in safety features that may not

work if altered.

3. When wiring an electrically driven device, follow all electrical and

safety codes, as well as the most recent Canadian Electrical Code (CE)

and Canadian Centre for Occupational Health and Safety

(CCOHS).

CAUTION! All wiring should be performed by a qualiﬁed electrician.

SPECIFIC SAFETY PRECAUTIONS

To avoid possible electric shock or personal injury when using the analog

multimeter, follow these guidelines:

1. Do not use the meter if it is damaged. Before you use the meter,

inspect the case. Pay particular attention to the insulation surrounding

the connectors.

2. Inspect the test leads for damaged insulation or exposed metal.

Replace damaged test leads before you use the meter.

3. Do not use the meter if it malfunctions. Protective features may not

work. When in doubt, have Princess Auto Ltd. service the multimeter.

4. Do not operate the meter around explosive gas, vapor, or dust as an

electric spark may cause the gas vapour or dust to ignite.

5. Do not apply more than the rated voltage, as marked on the meter,

between terminals or between any terminal and earth ground.

6. When measuring current, turn off power to the circuit before

connecting the meter. Remember to place the meter in series with

the circuit.

7. Keep your ﬁngers behind the probe’s ﬁnger guards when testing an

electrical current.

8. Do not operate the meter with the battery cover or portions of the case

missing or loose.

9. To avoid electric shock, do not touch any naked conductor with your

hand or skin. Do not ground yourself while using the meter.

10. CAT II - Measurement Category II is for measurements performed

on circuits directly connected to a low voltage installation. (Examples

are measurements on household appliances, portable tools and

similar equipment). Do not use the meter for measurements within

Measurement Categories III (circuit breakers or distribution boards)

and IV (Utility level devices).

TOOL USE AND CARE

1. This tool was designed for a speciﬁc function. Do not modify or alter

this tool or use it for an unintended purpose.

2. Securely hold this tool using both hands, unless it is designed for

single hand use. Using a tool with only one hand can result in

loss of control.

3. Maintain tools with care (see Maintenance).

UNPACKING

1. Carefully remove the parts and accessories from the box. Retain

packaging material until you have carefully inspected and satisfactorily

installed or operated the tool.

2. Make sure that all items in the parts list are included.

3. Inspect the parts carefully to make sure the tools and accessories were

not damaged while shipping.

WARNING! Do not operate the tool if any part is missing. Replace

the missing part before operating. Failure to do so could result in a

malfunction and serious personal injury.

PARTS IDENTIFICATION

Contents: Analog Multimeter with built in test leads.

ASSEMBLY

The Analog Multimeter comes preassembled.

OPERATION

CAUTION! To avoid possible damage to the multimeter or to the

equipment under test, follow these guidelines:

1. Use the proper function and range for your measurements.

2. Before rotating the Range Selection Switch to change functions,

disconnect test leads from the circuit under test.

NOTE: Be sure to check battery power level before each use.

SCALE INSTRUCTION

There are ﬁve scales on the multimeter display.

OHMS - The upper scale is for

resistance measurement.

DCVmA - The second scale is for

DC voltage measurements and DC

current measurements.

ACV - The third scale is for

AC voltage measurements.

BAT - The fourth scale is for

the battery test

dB - The ﬁfth scale is for decibels.

MEASUREMENT INSTRUCTIONS

1. Before measurement, adjust the Zero Pin until the pointer is directly

over the three black zeros at the left end of the scale.

2. The measuring range selected should be more than the value to

be measured.

3. Verify the meter is operating correctly by measuring a known voltage

before use.

MEASURING DC VOLTAGE

CAUTION! The Digital Multimeter is a CAT II device. Measuring a DC

voltage that exceeds 250 V will exceed the safety limits of the device

and could result in an electric shock to the user or damage to

the meter.

1. Set the Range Selection Switch to desired DC voltage range . .

If the voltage to be measured is not known beforehand, set the range

switch to the highest range and then switch down to the next range

until a satisfactory reading is obtained.

2. Touch the red test probe’s tip to the positive side of the circuit to be

measured and the black test probe’s tip to the negative side of

the circuit.

3. Use the DC Voltage Accuracy chart to determine the DC

Voltage measurement.

MEASURING DC CURRENT

1. Set the Range Selection Switch to desired DC current range .

If the magnitude of the current is not known beforehand, set the range

switch to the highest range and then switch down to the next range

until a satisfactory reading is obtained.

2. Turn off power to the circuit that you want to measure and discharge

all capacitors.

3. Break the circuit path so the current cannot pass through the circuit.

4. Touch the red test probe’s tip to the positive side of the break and the

black test probe’s tip to the negative side of the break.

5. Turn on power to the circuit, then read the display.

6. Use the DC Current Accuracy chart to determine the measurement.

MEASURING AC VOLTAGE

CAUTION! The Digital Multimeter is a CAT II device. Measuring an

AC Voltage that exceeds 250V rms will exceed the safety limits of the

device and could result in an electric shock to the user or damage to

the meter.

1. Set the Range Selection Switch to desired AC voltage range . If

the magnitude of the voltage is not known beforehand, set the range

switch to the highest range and then switch down to the next range

until a satisfactory reading is obtained.

2. Connect the test probe tips across the circuit.

3. Use the AC Voltage Accuracy chart to determine the

AC voltage measurement.

MEASURING RESISTANCE

NOTE: Before measuring in-circuit resistance, make sure that all power to the

circuit has been turned off and all capacitors are fully discharged.

1. Set the Range Selection Switch to desired Ω range.

2. Short the test probe tips, then adjust the Zero Adjustment Knob until

the point is in the 0 position of the OHMS scale.

NOTE: If it is not possible to set the point to the 0 position, the battery is low

and should be replaced (see Troubleshooting).

3. Connect the test leads across the load to be measured.

4. Read the top scale and multiply the reading by the factor on the

selected range, either 1K (1000) or 10, to obtain the

measurement results.

MEASURING DECIBEL

Decibel is measured in the same way as the AC voltage, but the dB scale is

read instead.

1. Set the Range Selection Switch to one of the choices in AC voltage.

2. Connect the test probe tips across the circuit.

3. Use the AC Voltage Accuracy chart to determine the

AC voltage measurement.

NOTE: When measuring a signal that contains a direct current, a 0.1 µF block

capacitor with a voltage endurance of more than 250V should be connected

in series.

BATTERY TEST

1. Set the Range Selection Switch to the desired BAT. range (9V or 1.5V).

2. Touch the red test probe’s tip to the positive terminal of the battery to

be tested and the black test probe’s tip to the negative terminal of

the battery.

3. There are three ranges:

a. GOOD indicates the battery still has a charge.

b. BAD indicates the batter is low.

c. ? indicates the battery’s condition is marginal.

MAINTENANCE

1. Maintain the device with care. A tool in good condition is efﬁcient,

easier to control and will prevent unnecessary problems.

2. Maintain the tool’s label and nameplate. These carry important

information. If unreadable or missing, contact Princess Auto Ltd.

for replacements.

CAUTION! Only qualiﬁed service personnel should repair the tool.

DISPOSING OF TOOL

If your tool has become damaged beyond repair, do not throw it out. Bring it to

the appropriate recycling facility.

TROUBLE SHOOTING

Bring the tool to the nearest Princess Auto Ltd. for repairs. If unable to do so,

have a qualiﬁed technician service the tool.
