5. Calibration and After-sales Service
Should any failure occur while you are using the tester, follow the instructions
given below. If the tester still fails to operate correctly and needs repair, con-
tact the vendor from whom you purchased the instrument or the nearest
Yokogawa M&C sales office.
Condition Possible
Cause
Remedy
Display blanks after
power-on
Battery is improperly installed.
Battery is exhausted.
Install the battery correctly.
Replace the buttery.
Display reading
remains frozen.
Data hold button is pressed in.
Peak hold switch is at ON
position.
Release data hold button.
Set peak hold switch to OFF
position.
Transformer jaws buzz
when measuring large
current.
-----------------
This is not a failure
The lowest digit of
reading is unstable
-----------------
This is not a failure. The
instrument is highly accu-
rate, so it senses slight
variations in the current
under test.
Output cable
(Model 91020) does not
output voltage.
The cable is open circuit.
Check the cable for an open
circuit.
Calibration
It is recommended that the instrument be calibrated once every year.
