 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…"
