Four single-ended voltage inputs and the two differential inputs
4-20mA transmitter
4-20mA receiver
Calibrating the Voltage Outputs
The JAZ-INDY module provides four analog voltage outputs on its 26-pin connector (outputs 14 are
mapped to pins 5, 14, 23, and 4 respectively, where pins 2, 12, or 15 can be used as analog ground).
►
Procedure
1.
Connect an external, calibrated voltmeter (providing at least 5 total digits resolution) to each
output pin to calibrate it. No load should be connected to the output pin; it should be connected
to a voltmeter and nothing else.
2.
Set the output voltage (in counts) until the voltmeter reads as close as possible to -4.5V. Record
this value to be used later.
3.
Set the output voltage (in counts) until the voltmeter reads as close as possible to 0.0V. Record
this value to be used later.
4.
Set the output voltage (in counts) until the voltmeter reads as close as possible to 4.5V. Record
this value to be used later.
5.
Using the Jaz menu or OceanView software, select the voltage output to be calibrated:
a.
Select Minimum, then change the voltage to -4.5 and set the counts to the value you
measured in Step 2.
b.
Select Zero and enter the counts measured in Step 3.
c.
Select Maximum, then change the voltage to 4.5 and set the counts to the value you measured
in Step 4.
6.
Repeat this procedure for each of the output channels.
Calibrating the Voltage Inputs
Once the voltage outputs are calibrated, they can be used to calibrate the voltage inputs. These can be
found on pins 3, 13, 22, and 21. Note that the output voltage may sag slightly when connected to the
voltage inputs, so it is necessary to keep the voltmeter connected to the joined input and output pins to
compensate.

Procedure
1.
Set the output voltage (in counts) until the voltmeter reads as close as possible to -4.5V.
2. Using the Jaz menu or OceanView software (see
Calibrating the 4-20mA Transmitter
), select the
voltage input to be calibrated:
a.
Select Minimum, and change the voltage to -4.5V. Then select Sample at -4.50V. This will
update the counts automatically.
