Troubleshooting:
Problem :
The unit says “battery bad replace now” and
won’t go to next screen
Solution : Replace battery
Problem :.
It won’t switch modes from low range to high
range to pink noise
Solution : Make sure the impedance being read is greater
than 0.5 ohms. If not disconnect harness, change modes,
then reconnect.
Problem : The Z reading says open
Solution : The impedance being measured is over 100
ohms. Test the harness by shorting the alligator clips
together, if harness is good impedance should be less than
0.50 ohms. If harness is good, then reading was accurate.
Problem : The IM-SG keeps turning off
Solution : The IM-SG has an auto turn off timer; it will
operate for approximately
8 minutes after the “On” button is
pressed. This is to prevent it from eating your battery when
you forget to turn it off. If you are in the middle of using it
and need it to stay on, press the "On" button occasionally,
this will reset the timer.
Problem : Some high frequency chirping can be heard
when generating frequencies under 200 Hz.
Solution : This is normal and should not affect any
measurements or readings.
