The Triplett 3022 Model 310-C Handheld Analog Volt-Ohm Meter with Polarity Reversing is a hand-sized VOM with all the versatility and performance of larger, more expensive bench-size models. It offers diode overload protection against damage to the meter movements caused by accidental overloads. A fuse is used to protect the RX1 range. The fuse and batteries can be easily replaced by removing the back cover.

Small enough to be carried in your tool box, glove compartment, brief case, or shirt pocket, the Model 310-C features 20,000 ohms per volt DC and 15,000 ohms per volt AC sensitivity. Additionally, the 310-C incorporates a convenient Polarity Reversing Switch which electrically reverses the test lead connections easily correcting accidental downscale readings.

Versatility and readability have not been sacrificed in order to provide a portable VOM. The Model 310-C has 18 different ranges that can be easily read on only 3 clearly defined scale areas. A single selector switch allows you to switch easily from range to range and function to function.
