Calibrating the Series 96

Warm up the unit (20 minutes). To enter a calibration menu, enter the Factory Page by holding down the ˆ and ‰ keys for six seconds. Once in the Factory Page [Fcty] use the Up-arrow ¿ or Down-arrow ¯ Key to select a menu. The last three menus on the Factory Page are Calibration 1 Menu [cin1], Calibration 2 Menu [cin2] and Process Output Calibration Menu [cout].

You can restore the original factory calibration with Restore Factory Calibration [`rSt] (Calibration 1 Menu) or revert to the default parameter range selections with Default Settings [dFLt] (Calibration 1 Menu).

Thermocouple Input Procedure

Equipment

•Type J reference compensator with reference junction at 32°F/0°C, or type J thermocouple calibrator to 32°F/0°C.

•Precision millivolt source, 0 to 50mV minimum range, 0.002mV resolution.

Input 1 Setup and Calibration

1.Connect the correct power supply to terminals 8 and 9 (see Series 96 User’s Manual).

2.Connect the millivolt source to terminals 6 (-) and 7 (+) with copper wire.

3.Enter 50.000mV from the millivolt source. Allow at least 10 seconds to stabilize. Set Thermocouple Calibration, 50mV [tc50] (Calibration 1 Menu) to [`yES]. Press the Advance Key ‰ to store 50.000mV input and move to the next prompt.

4.Enter 0.000mV from the millivolt source. Allow at least 10 seconds to stabilize. Set Thermocouple Calibration, 0mV [tc00] (Calibration 1 Menu) to [`yES]. Press the Advance Key ‰ to store 0.000mV input and move to the next prompt.

5.Disconnect the millivolt source and connect the reference compensator or thermocouple calibrator to terminals 6 (-) and 7 (+). With type J thermocouple wire, if using a compensator, turn it on and short the input wires. When using a type J calibrator, set it to simulate 32°F/0°C. Allow 10 seconds for the controller to stabilize. Set Thermocouple Calibration, 32° [tc32] (Calibration 1 Menu) to [`yES]. Press the Advance Key ‰ to store type J thermocouple calibration and move to the next prompt.

6.Rewire for operation and verify calibration.

RTD Input Procedure

Equipment Required

•1kΩ decade box with 0.01Ω resolution.

Input 1 Setup and Calibration

1.Connect the correct power supply to terminals 8 and 9 (see Series 96 User’s Manual).

2.Short terminals 5, 6 and 7 together with less than 0.1Ω . Set Ground [`gnd] (Calibration 1 Menu) to [`yES]. Press the Advance Key ‰ to store ground input and move to the next prompt.

3.Short terminals 5 and 7 together with less than 0.5Ω . Set Lead Resistance Calibration [LEAd] (Calibration 1 Menu) to [`yES]. Press the Advance Key ‰ to store the lead resistance and move to the next prompt.

4.Connect the decade box to terminals 5 (S2), 6 (S3) and 7 (S1), with 20to 24-gauge wire.

5.Enter 15.00Ω from the decade box. Allow at least 10 seconds to stabilize. Set RTD Calibration, 15Ω [r`15] (Calibration 1 Menu) to [`yES]. Press the Advance Key ‰ to store the 15.00Ω input and move to the next prompt.

6.Enter 380.00Ω from the decade box. Allow at least 10 seconds to stabilize. Set RTD Calibration, 380Ω [r380] (Calibration 1 Menu) to [`yES]. Press the Advance Key ‰ to store the 380.00Ω input and move to the next prompt.

7.Rewire for operation and verify calibration.
