Intelligent Auto-Power-Off (APO)
The Auto-Power-off (APO) mode turns the meter off automatically to
extend battery life after approximately 32 minutes of no specified
activities, where applicable:
1) Rotary switch or push button operations
2) Significant measuring readings of above 8.5% of ranges
3) Non-OL readings for Resistance, Continuity or Diode function
4) Non-zero readings for Hz function
5) Significant movement indication as in Phase Rotation functions
In other words, the meter will intelligently avoid entering the APO
mode when it is under normal measurements. To wake up the meter
from APO, press the
SELECT button momentarily or turn the rotary
switch OFF and then back on. Always turn the rotary switch to the
OFF position when the meter is not in use
5) MAINTENANCE
WARNING
To avoid electrical shock, disconnect the meter from any circuit,
remove the test leads from the input jacks and turn OFF the meter
before opening the case. Do not operate with open case.
Trouble Shooting
If the instrument fails to operate, check batteries and test leads etc.,
and replace as necessary. Double check operating procedure as
described in this user’s manual.
If the instrument voltage-resistance input terminal has subjected to
high voltage transient (caused by lightning or switching surge to the
system under test) by accident or abnormal conditions of operation,
the protective impedance components in series might be blown off
(become high impedance) like open fuses to protect the user and the
instrument. Most measuring functions through this terminal might
then be open circuit. Such components should only be replaced by
qualified technician. Refer to the LIMITED WARRANTY section for
obtaining warranty or repairing service.
Accuracy and Calibration
Accuracy is specified for a period of one year after calibration.
