* Approximate value corresponding to the automatic change of scale (when red light lit:
multiply the reading by 10 to get the result)
Use of the guarded terminal:
To avoid disruption of the insulation
resistance measurement by superficial
earth leakages, connect a safety circuit
using safety terminal “G”.
