CHECKING

1) Terminal wiring: Check that all cables are correctly con-

nected according to the connection diagram.

2) Input: Check current with an ammeter. Be sure that the

connected transmitter allows the unit’s load value [250 Ω

+ output load resistance].

3) Output: Check that output load is within the permissible

limit of 600 Ω.

ADJUSTMENT PROCEDURE

This unit is calibrated at the factory to meet the ordered

speciﬁcations, therefore you usually do not need any cali-

bration.

For matching the signal to a receiving instrument or in case

of regular calibration, adjust the output as explained in the

following.

■HOW TO CALIBRATE THE OUTPUT SIGNAL

Use a signal source and measuring instruments of sufﬁcient

accuracy level. Turn the input signal on and warm up for

more than 10 minutes.

1) SPAN: Apply 100% input and adjust output to 100%.

MAINTENANCE

Regular calibration procedure is explained below:

■CALIBRATION

Warm up the unit for at least 10 minutes. Apply 25%, 50%,

75% and 100% input signal. Check that the output signal

for the respective input signal remains within accuracy de-

scribed in the data sheet. When the output is out of toler-

ance, recalibrate the unit according to the “ADJUSTMENT

PROCEDURE” explained earlier.
