User manual SEFELEC 5x Series 77 v1.06
THE FOLLOWING ERROR MESSAGES:
"SAFETY LOOP OPEN": the safety loop is not closed, there is no connection between
the points 1-9 or 2-10 of connector C5 on the rear panel of the device. Press OK to
acknowledge the message
"OVER RANGE": the insulation resistance of the sample under test is higher than
the measurement possibilities of the device (> 2 TΩ or other value according to the
measurement voltage)
"SATURATION": the insulation resistance of the sample under test is lower than the
measurement possibilities of the device (< 100 kΩ)
"CHARGE…": The measurement voltage has not reached its final value. The voltage
generator charges the capacity of the sample under test. This message should appear
momentarily when switching to measuring mode. If this message persists the measure-
ment voltage requested cannot be supplied to the resistance measured.
Check the characteristics of the voltage generator.
"VOLTAGE ERROR": If a measurement time is defined, and during the test the mes-
sage: "Charge..." is displayed permanently, at the end of the measurement time the test
is declared NG and the message: "Voltage error" indicates the cause.
If necessary, refer to the information on the message: "Charge…"
