The switch selects whether the high-limit PASS-FAIL judgment in the insulation resistance test is
to be done or not.
[5] REFERENCE SET
The switches are for setting a PASS-FAIL judgement reference value for insulation resistance test.
When neither the UPPER switch nor the LOWER switch is pressed, the ohmmeter indicates the
value of measuring resistance.
When the LOWER switch is pressed, the ohmmeter indicates the low limit reference value for
PASS-FAIL judgment; when UPPER switch is pressed, the ohmmeter indicates the high limit refer-
ence value. When both switches are pressed, the LOWER switch has a priority. The limit reference
values are adjustable with the potentiometers located at right and left of the switches.
