INPUT SENSIVITY

Strain meters for brid

g

e type transducers are confi

g

ured for an input sensivity

(transducer output in mV) of 100mV at full-scale.

To modifie this value, replace the resistor R6 for one whose value is given by

the following formulas:

where: mV = cell sensivity (in mV) for the constant current that supplies the

meter (1.5mA).

If the transducer's specifications are given for an excitation current different

from 1.5mA, apply the proportional factor to obtain the mV output at a

current of 1.5mA.

DISPLAY READING

After configuring the input sensivity, apply the following formula to determine

the value of R18 in order to get the desired display readout (VD).

R18)ohm) = ((553*(2500 - VD)) / VD) - 100

With the resistance value obtained from the formula, the span adjustment

margin is set to 20% of the display readout VD.

COMMON MODE REJECTION RATIO

Tie terminals B and C togheter at the input connector and connect two

resistors of 1Mohm from this point to pin A and pin D as it is indicated in the

figure at right.

Adjust the ZERO potentiometer until 0V are obtained between its middle point

(slider) and the meter ground (taken at the point -M- of the capacitor).

Adjust finally the RP3 potentiometer until the display registers 0V.

DISPLAY RANGE ADJUSTMENT

Connect two resistors of 1kohm between the input C and pins A and D in

order to reference this input to the tranducer's excitation.

N = 2750 / mV R6(ohm) = 12000 / N - 3

Connect between pins B and C an accurate reference millivoltmeter replacing

the full-scale transducer's signal and adjust the SPAN potentiometer until the

display reads the desired value.

Shortcircuit pins B and C and readjust 0V with the ZERO potentiometer.
