Low Voltage
Settings
LV Insulation Resistance
(LV Insul Res)
The LV Insulation Resistance setting only affects the low voltage test where the basic cable
pattern and gross insulation problems are identified. This setting determines how high the
insulation resistance must be between cable nets to pass the low voltage test. The tester
displays SHORT for an unintended resistance between nets that is less than the
LV Insulation
Resistance setting.
In addition, the
LV Insulation Resistance setting determines at what resistance intended
connections are considered open , as opposed to having high resistance.
Guidelines on LV Insulation Resistance
The factory default of 100K
Ω should work well for most cable testing applications. The higher
you raise the LV Insulation Resistance setting, the longer it takes for the tester to perform the
low voltage part of the cable test.
Note: Resistances above the LV Insulation Resistance setting will be ignored during a learn.
