CHAPTER 9

PROGRAMMING GROUP 2: METER CALIBRATION

9.1STANDARD CALIBRATION

WARNING - READ THIS SECTION CAREFULLY BEFORE PROCEEDING

⌦Calibration does not need to be accomplished to change CT or PT ratios. (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.

⌦BEFORE calibrating any channel, make note of its Full Scale Setting (see Ch. 8). Set the Full Scale in accordance with Table 9-1for calibration. Restore original Full Scale Setting when calibration is completed.

⌦The first function in GROUP 2 (STD.CORR) is NOT to be changed by the user. Please make

note of the value here ( ) before using any other function in this Group. If the STD.CORR value is inadvertently lost or changed, contact the factory for assistance.

All sensitive electronic measuring devices drift slightly over time, requiring periodic calibration. We recommend returning the meter to the factory on a yearly basis.
