any damage caused by possible battery leakage

SPECIAL PRECAUTIONS FOR OPERATION:

ATTENTION: BEFORE OPERATION:

MEASURING DC VOLTAGE:

MEASURING AC VOLTAGE:

MEASURING DC CURRENT:

1. Check batteries. When the battery voltage drops below correct operational range;“ ” symbol will

appear on the LCD display and the batteries will require replacing

2. Pay close attention to the symbol beside the input jack which shows that the input voltage or

current should be within a speciﬁed value

3. The RANGE switch should be positioned to the desired range of measurement before operation

1. Connect the black test lead to “COM” socket and red test lead to the “VΩ” socket

2. Set the selector switch to desired “mV “ or “ V “ position and connect the probes across the

device under test

3. Read the result from the LCD panel

1. Connect the black test lead to “COM” socket and red test lead to the “VΩ” socket

2. Set the selector switch to desired “V~” position and connect the probes across the device

under test

3. Read the result from the LCD panel

1. Set the selector switch to desired “200A“or “1000A “ position

2. Press the “REL” the display show “0”

1. Set selector switch to desired “400A/1000A˜” position

2. Open the clamp by pressing the jaw-opening handle and insert the cable (one cable only) into the

jaw

3. Close the clamp and take the reading from the LCD panel

Note:

1. Before taking this measurement, disconnect the test lead from the meter for safety

2. Push the D.HOLD button to read the result later

3. AC Current range measurement is between 400A - 800A only

1. Connect the black test lead to “COM” socket and red test lead to the “VΩ” socket

2. Set the selector switch to the “Ω” position, push the "SELECT" button to select resistance

measurement if it is not the ﬁrst option

3. Connect the probes across the device under test

less than approx. 90Ω

TEMPERATURE MEASUREMENT:

MEASURING FREQUENCY:

DIODE TESTING:

AUDIBLE CONTINUITY TEST:

Caution: Ensure the power is isolated to the circuit. Max. Input overload: 250V rms<10sec

1. Press “REL”, to measure the relative value: “REL” appears on the display, the auto range mode will

be changed to manual range mode. Press again, and “REL” disappears, you return to auto range

mode. NB: the meter cannot go back to auto range mode whilst in” Hz” measurement, and will not

measure the relative value
