Watlow Series 96 Calibration ■ 7
Output 4 Setup and Calibration
1. Connect the correct power supply to terminals 8 and 9 (see Series 96 User’s Manual).
Milliamperes
2. Connect the volt/ammeter (set to milliamperes) to terminals 20 (-) and 21 (+).
3. At Output Calibration 4, 4mA [4``4] (Process Output Calibration Menu) enter the
reading from the ammeter. The unit should stabilize within one second. Repeat until the
ammeter reads 4.00mA, ±0.1mA. Press the Advance Key ‰ to store the value and move
to the next prompt.
4. At Output Calibration 4, 20mA [4`20] (Process Output Calibration Menu) enter the
reading from the ammeter. The unit should stabilize within one second. Repeat until the
ammeter reads 20.00mA, ±0.1mA. Press the Advance Key ‰ to store the value and move
to the next prompt.
Volts
5. Connect the volt/ammeter (set to volts) to terminals 19 (+) and 20 (-).
6. At Output Calibration 4, 1V [4``1] (Process Output Calibration Menu) enter the
reading from the voltmeter. The unit should stabilize within one second. Repeat until
the voltmeter reads 1.00V, ±0.1V. Press the Advance Key ‰ to store the value and move
to the next prompt.
7. At Output Calibration 4, 10V [4`10] (Process Output Calibration Menu) enter the
reading from the voltmeter. The unit should stabilize within one second. Repeat until
the voltmeter reads 10.00V, ±0.1V. Press the Advance Key ‰ to store the value and move
to the next prompt.
8. Rewire for operation and verify calibration.
