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.
Accuracy specifications are valid for a period of one year after calibration, when measured at an operating temperature of 18°C to 28°C and at A maximum of 80% relative humidity.
To perform the following tests, it is not necessary to open the case, no Adjustments are necessary. Merely make the required connections, apply the designated inputs, and determine if the reading on the Meter display falls within the acceptable range indicated.
If the Meter fails any of these tests, it needs calibration adjustment or repair.
Testing the Display
