1/8 DIN/NEMA Digital Panel Meters
The NLS RM Series panel meters are customized to fit your needs, with over 2,000
variations available. Configured in the industry-standard 1/8 DIN/NEMA-style case, they
are ideal for both OEM and replacement applications. These rugged meters are DC-powered,
DC-reading (AC-powered and AC-reading are options) and bipolar, with presettable decimal
point and either LED or LCD display. An extra large 0.8-inch LED display is also available
on some RM Series meters. A full selection of ranges (200mV, 2V, 20V, 200V and 1000V) is
available.

1To order current measurement add /CS suffix to the model number. 2To
order AC reading, add AC to the model number; 3to order ohms reading, add ohms;
4to order AC power, add 120 or 240; 5to order +5, 12, 24, or 28Vdc,
add the number and Vdc (e.g., 12Vdc) to the end of the model number. List multiple
additions for multiple options.
