The Triplett 3067 Model 310-TEL Handheld Analog Volt-Ohm Meter L is a handheld VOM with all the versatility and performance of larger, more expensive bench-size models. It offers diode overload protection against damage to the meter movement 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-TEL allows you to have 20,000 ohms per volt DC and 5,000 ohms per volt AC sensitivity wherever you need it.

A convenient Polarity Reversing Switch electrically reverses the test lead connections, correcting accidental downscale readings and permitting "capacitive kick" readings on the Ohmmeter ranges.

Versatility and readability have not been sacrificed in order to provide a portable VOM. The Model 310-TEL offers 16 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.
