Required Equipment; Accuracy Test - Fluke 28 II Ex Calibration Information Manual

Required Equipment

Table 3 is a list of the equipment necessary to do performance tests on the Meter.
Recommended Equipment
Calibrator
(Fluke 5520A or equivalent)
K-type Thermocouple, mini-plug
on both ends

Accuracy Test

To measure the accuracy of the Meter, set the Calibrator to the Calibrator output
parameters shown in Table 4. Make sure the UUT measurement is between the low and
high limit shown in the table.
