(See GROUP 1) Meter calibration cannot be performed if the meter is installed for service. The sensing must be connected to a power supply with variable voltage and separate current outputs. The calibration procedure requires highly accurate and stable input signals. Incorrect readings result from improper calibration procedures. If unsure, return unit to the factory for calibration. EFORE calibrating any channel, make note of its Full Scale Setting (see hp. 4). Set the Full Scale in accordance with Table 5-1 for calibration. Restore original Full Scale Setting when calibration is completed. The first function in GROUP 2 (STD.ORR) is OT to be changed by the user. Please make note of the value here ( ) before using any other function in this Group.
