Before any change of ranges, ensure that the
signal at HM8012 does not represent an
unacceptable load of the object under
examination.
For the link between the calibrator and HM8012,
shielded cables must be used to prevent any
unwanted influence caused by the measurement
signal.
a) DC voltage ranges
b) AC voltage ranges
(1) = 50 Hz to 10 kHz
(2) = 20 Hz to 20 kHz
(3) = 50 Hz to 1 kHz
(4) = 20 Hz to 1 kHz.
c) DC ranges
Subject change without notice
d) AC ranges (f = 400 Hz)
e) Resistor ranges
Calibration sequence
HM8012 is calibrated for the greater part by
software. Access to the adjustment mode is
obtained by turning
simultaneously pressing the AUTO (16) and
BEEP(3) keys.
Wait for the CAL message to appear on the
display. Release the keys. The instrument
indicates a calibration step. The first character
indicates the measured magnitude, followed by
the standard value to be applied to the input. In
this mode, the keys play a particular function as
detailed below.
