Which prefix indicates negative DC energy (high voltage) instrument?

Explanation:
In this labeling system, prefixes on instruments indicate the energy type and polarity of what they connect to. The prefix that marks a negative DC high-voltage instrument is Ch. This designation signals that the device is part of the negative-polarity, high-voltage DC circuit, guiding you to apply the appropriate safety measures and measurement approach. The other prefixes (Cg, Co, Cos) are used for different energy types or categories and would not indicate the negative DC high-voltage instrument. When you encounter a device labeled with Ch, treat it as a high-voltage, negative-polarity instrument and follow the relevant safety procedures.
