## Overview

The Megger BT51/120 Digital Low Resistance Ohmmeter offers precise ±0.1% accuracy with a powerful 2 Amp test current, displayed on a bright 3-1/2 digit LED screen. Housed in a rugged, shockproof, and weatherproof case, it’s built for professional field use. Safety features include relay protection against live voltages and neon warnings, making it an essential tool for electrical testing in challenging environments.

## Description

The BT51 Low resistance ohmmeter makes measurements by passing a current through the conductor under test and also monitoring the voltage across it. The test current is limited by a simple current limiting circuit and is measured by monitoring the voltage across a resistor. The instrument has a 3-1/2 digit LED display to facilitate use in low light levels. 2 LED’s on the front panel indicate battery condition and whether test current is flowing when a measurement is being made. A neon lamp indicates the presence of a dangerous voltage if the test spikes are accidentally placed across a live circuit. This warning takes place whether or not the instrument has been switched on. The ohmmeter is protected up to 240 V a.c. by a relay circuit that keeps the instrument in a safe mode isolated from the mains supply. Again, this safeguard is effective whether or not the instrument has been switched on. Operation of the instrument is simple, there being only one range switch to set. Duplex hand spike test leads are supplied. The instrument is built into a robust, portable case that is weatherproof and shockproof and has a hinged, detachable lid. Specifications: test current: 2 Amps nominal, with up to 2 ? across the C terminals. Accuracy (0 to 50 degree C): +/-1 percent of reading +/-2 digits. Display: 3-1/2" digit LED display. Temperature range: operating: 0 to 50 degree C (32 to 122 degree F). Storage: -20 to +50 degree C (-4 to 122 degree F). Protection: relay protection for up to 240V mains supply applied from C1/Pl to C2/P2 100 mA (T) fuse, 20 x 5 mm, ceramic (for charging circuit). Power supply: 4 Ah capacity NiCad rechargeable cells with internal charging unit. Normal charging time of 10 hours on 240V, 50 Hz mains supply. Safety: The instrument meets the requirements for IEC 610101-1. The instrument is intended for use with non powered circuits only. EMC in Accordance with IEC61326-1. Measures 13-1/2" width by 9-5/8" height by 6-1/4" depth.

## Features

- High test current - 2 a.c.
- 4 Terminal measurement
- 3-1/2" digit LED display, which is helpful in a poorly lit environment
- Robust, shockproof, weatherproof, portable case
- Can use very long test leads
