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.
For operating instructions, see the
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 a maximum of 75% 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
Turning the meter on from the “OFF” position, the meter will full display all segment and symbols. Compare the display with the example in Figure 2.
