Accuracy Tests

Accuracy specifications are valid for 1 year after calibration adjustment when

measured at an operation temperature of 18 °C to 28 °C. Allow the Meter to

stabilize at room temperature prior to performing the accuracy tests.

The following tables list the required performance test points for verifying Meter

accuracy. Zero the Meter prior to completing each measurement point.
