5.5 Input Calibration Procedure

Introduction
Before performing this procedure, be sure the recorder is wired for calibration as described in Subsection
5.4. Apply power and allow the recorder to warm up for 30 minutes before you calibrate.
Make sure "LOCK" is set to "NONE" (see Section 4 - Configuration, Startup and Operation of Recorder
with Display).
ATTENTION
For Milliamp inputs, be sure the current source is at zero before switching on the calibrator.
Do not switch the calibrator on/off while it is connected to the recorder's input. Failure to observe
this precaution could result in damage to input circuits.
Calibration procedure sequence
The calibration procedure sequence for all inputs is listed in Table 5-9. The calibration procedure for inputs
1 and 2 is identical. The displays indicate the input number.
