Function Test - Hameg Instruments HM8010 Manual

F u n c t i o n T e s t

Function Test

This test should help verify, at certain intervals,
the functions of HM8010 without any great
expenditure in measurement instruments. To
achieve thermal balance, the module and the
basic instrument, in its case, must be energized
for at least 60 minutes before the test begins.
Measurement equipment used
AC/DC calibrator for instance Fluke 5101B / Fluke
5700A / Rotek 600
Resistors of 5 kW, 50 kW, 500 kW 0.01% for
instance model S102 J by Vishay
Resistors 500 kW, 5 MW 0.02%, for instance
models CNS020 by Vishay.
Test procedure
If one of the indicated calibrators is available or
if precision calibrators are appropriate, all the
HM8010 measurements ranges can be checked
using the following tables which indicate the limit
values. Recalibration, however, should only be
performed if the appropriate precision calibrator
is available.
Before any change of ranges, ensure that the
signal at HM8010 does not represent an
unacceptable load of the object under exa-
mination. For the link between the calibrator and
HM8010, shielded cables must be used to prevent
any unwanted influence caused by the
measurement signal.
