Performance Tests
The following performance tests verify the complete operability of the Meter and check
the accuracy of each Meter function against the Meter’s specifications. Performance tests
should be performed annually to ensure that the Meter is within accuracy specifications.
Accuracy specifications are valid for a period of one year after calibration adjustment,
when measured at an operating temperature of 18
°
C to 28
°
C and at a maximum of 90 %
relative humidity.
To perform the following tests, it is not necessary to open the case. No adjustments are
necessary. Make the required connections, apply the designated inputs, and determine if
the reading on the Meter display falls within the acceptable range indicated.
Note
If the Meter fails any of these tests, it needs calibration adjustment or repair.
