6 ■ Calibration Watlow Series 96
Process Output Procedures
Equipment
• Precision volt/ammeter with 3.5-digit resolution.
Output 1 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 13 (+) and 14 (-).
3. At Output Calibration 1, 4mA [1``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 1, 20mA [1`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 14 (-) and 15 (+).
6. At Output Calibration 1, 1V [1``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 1, 10V [1`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.
Output 2 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 17 (-) and 18 (+).
3. At Output Calibration 2, 4mA [2``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 2, 20mA [2`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 16 (+) and 17 (-).
6. At Output Calibration 2, 1V [2``1] (Process Output Calibration Menu) enter the
reading from the volt. 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 2, 10V [2`10] (Process Output Calibration Menu) enter the
reading from the volt. 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.
