These buttons increase / decrease
the analog output signal level (not the
value on the display)
by 100, 10 or 1 counts.
Continue adjustments until the
voltage measured at the output of the
analyzer and/or the input of the
recording device matches the value
in the upper right hand corner of the
display (within the voltage tolerances
listed in the preceding table).
4.13.6.3. Manual Calibration of Analog Outputs Configured for Current Loop Ranges

The current loop output option (see Section 3.4.5) 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 4-12).
•
Adjustments to the output are made using the front panel touchscreen, 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.)
