Rugged, Dependable Design
Automatic Safety Check for grounded test cables
The BCM-44 and BCM-44B are state of the art current monitors designed for continuous operation during bare-hand work. The BCM has an adjustable set point (5 presets also available on BCM-44B) between 1 and 400 microamperes AC or DC. A 90-dB horn sounds an audible warning if this current set point is ever exceeded during use.
The BCM-44 and BCM-44B are extremely rugged and dependable current monitors. Designed for operation a variety of weather conditions, the BCM provides the security needed for bare-hand live-line work.

Additional Features of the BCM 44B:
Six-position function switch provides for the following:
1. Meter accuracy check using the internal precision current source
2. Test circuit for boom metering bands
3. Test circuit for hoses
4. Test circuit for leveling rods or fiber optics
5. Total test including the sum of all three circuits
6. Display variable set point
Also a push button is provided to check the continuity of each input
circuit.
Note: Daily use of this monitor does not eliminate the need to perform periodic over-voltage tests on aerial lift devices. The absolute minimum recommended over-voltage test should be a DC test of 2.1 times the line to ground exposure or an AC test of 1.5 times the line to ground exposure.
