Replacing The Fuses; Range Specifications - Extech Instruments EX310-NIST User Manual

REPLACING THE FUSES

WARNING: To avoid electric shock, disconnect the test leads from any source of voltage before
removing the fuse cover.
Disconnect the test leads from the meter.
1.
Remove the protective rubber holster.
2.
Remove the Phillips head screw located on the lower back of the instrument.
3.
Remove the fuse/battery compartment cover to access the fuses.
4.
Gently remove the fuse(s) and install new fuse(s) into the holder(s).
5.
Always use fuses of the proper size and value (200mA/600V fast blow for the mA / µA ranges,
6.
10A/600V fast blow for the A range).
Secure the fuse/battery compartment cover.
7.
Place the protective rubber holster on the meter.
8.
WARNING: To avoid electric shock, do not operate your meter until the fuse cover is in place and
fastened securely.

Notes: Accuracy specifications consist of two elements:
 (% reading) – This is the accuracy of the measurement circuit.
 (+ digits) – This is the accuracy of the analog to digital converter.
Accuracy is stated at 18
Range Resolution
Resolution & accuracy do not apply since the meter does not display the
100 to 600V
voltage in this mode. The lamp at the top of the meter's display flashes
when voltage is sensed and an audible warning will sound
