6. Connect the Product directly to the megohmmeter as shown in Figure 9.
Make sure you reverse the polarity.
Note
When you use the 100 G
Ω value on the Product for some
megohmmeters, the leads must be swapped between the HI and LO
ohms resistance output on the Product. The ground must be turned
on (Gnd On) when you swap HI and LO leads positions in the high
ohms resistance function. For example, to make a correct
measurement with the Quadtech 1865 Megohmmeter, connect the
HI terminal on the megohmmeter to the LO terminal on the Product
and connect the LO terminal on the megohmmeter to the HI terminal
on the Product. Turn the ground on and make the measurement.
