Typical settling time of the measurement as a function of the elements tested
These values include the influences on the auto-range and supply voltage regulation system due to the
charge of the capacitive component.
1 MΩ insulation
500 GΩ insulation
Discharge time of the tested element (across a 750 kΩ Ω Ω Ω Ω internal resistance) up to 25 V

Range of DAR and PI ratios : 0.000 to 9.999
Accuracy: ±5%
7.2.3 Continuity
Method: Voltage-current method according to EN 61557-4 (ed. 02/97)
Open-circuit voltage: Max. 12.4 V
Short-circuit current: > 200 mA
Max. voltage surge: 1200 V AC and DC for 10 seconds between the "+" and "-" terminals
660 V AC and DC between the "G" and "-" or "G" and "+" terminals
Test lead compensation:
R ∆ is measured for the test leads in short-circuit when in the SET-UP menu (see § 4.7), this value is
memorised and subtracted from all continuity measurements. The compensation is limited to 5 Ω.
Continuity measurement range: 0.01 to 39.99 Ω
Resolution : 0.01 Ω
