| |   Tri-Metric 2020 battery system monitor
The TriMetric battery monitors are designed to assist in battery care, conservation and system maintenance of battery powered systems that use storage batteries with system voltage from 12-48 volts. They provide the user with information on battery "volts", "amps" and "amp-hours" and the newest version also provides "battery percent full" information, based on measuring the amp-hours removed from the battery system. Reliability, accuracy and simplicity are key product objectives. The TriMetric requires an external shunt located near the batteries to measure "amps" and "amp-hours". The meter readout may be located hundreds of feet away from batteries and is usually connected to the shunt with a 4 wire cable.
The newest version of TriMetric (Model TM-2020) has been available since April 1998 and incorporates some "user friendly" improvements including a "Battery % full" display, and a "battery reminders" feature to help users to better care for batteries which should make it the more favored choice for most users. However all TriMetrics measure "volts" "amps" and "amp-hours" with the same accuracy.
This web page provides information about the TriMetrics which you may download and print on your printer, including specification, instructions, picture, wiring diagram and troubleshooting information. It provides some basic information on using the TriMetric or other similiar type meter for maintaining battery systems. Technical notes include information about shunts and 48 volt adapter and lightning protector.
