6.13.6.3. Manual Calibration of Analog Outputs configured for Current Loop Ranges
The current loop output option (see Section 5.4) uses a small converter assembly to change the DC voltage
output by the standard voltage output to a current signal ranging between 0-20 mA. Since the exact current
increment per voltage count varies from converter to converter and from instrument to instrument, analog
outputs with this option installed cannot be calibrated automatically and must be adjusted manually.
Adjusting the signal zero and full scale values of the current loop output is done in a similar manner as manually
adjusting analog outputs configured for voltage output except that:
In this case calibration is performed with a current meter connected in series with the output circuitry
(See Figure 6-6-15).
Adjustments to the output are made usi
ng the front panel keys, also in 100, 10 or 1 count increments,
but the change in the voltage driving the converter assembly is displayed on the front panel.
As before, adjustment of the output is performed until the current reading of the meter reaches the
desired point (e.g. 2 mA, 4 mA, 20 mA, etc.)
