2.r.Preparation for operation
M191 Insulation Tester Calibrator__________________ MEATEST. For application full
resistance range the relative humidity should not exceed %RH. 1. The sack contains silica gel bags avoid moisture
influence during transport and stocking.
• Connect rear panel grounding post with earthing ground (protection earth) individually using green/yellow
grounding lead, see fig. Before powering the instruments, place
it level surface.
• Switch the mains switch located the rear panel. Leave the cartoon with the calibrator for hours room temperature
before unpacking, especially during transport the cartoon was exposed temperature lower than °C.3 Power-on
• Before connecting the calibrator the mains, check the position the mains voltage selector located the
rear panel. Accuracy not guaranteed for operation in
relative humidity above %RH. s.
• Plug one end the power cord into the connector located the rear panel and connect the other end the
power cord into wall outlet.
