Insulation Tester Quick Reference Guide, PN 5304200.
Electrical Specifications
The Tester’s accuracy is specified for 1 year after calibration at operating
temperatures of 10 °C to 30 °C. For operating temperatures outside the range
(-10 °C to +10 °C and +30 °C to +50 °C), add ±0.25 % per °C for 5 % bands and
add ±1 % per °C for 20 % bands.
