FAQs

What is the maximum DC voltage that the Heathkit IM-5210 probe meter measures?

It measures extremely high DC voltages up to 40,000 volts, with a stated voltage range of 0–40 kV DC.

What safety precautions must be followed during use?

Always ensure the ground clip is connected to the chassis and the probe switch is OFF when not making a measurement. Never measure DC voltages in excess of 40,000 volts.

Why are careful solder connections emphasized in this guide?

Many returned kits fail due to poor solder connections. Carefully inspect, reheat doubtful connections, and recheck wiring as described in the “Soldering” section of the Kit Builders Guide.
