The PM-DC Series with DC current input models can be set to one of 4 input ranges from ±2.0000 mA with 0.1 µA resolution to ±5.000 A with 1 mA resolution. The DC voltage input models may be set to one of 6 input ranges from ±200.00 mV with 10 µV resolution to ±600.0 V with 0.1 V resolution.
The PM-RM Series with AC current input models can be set to one of 4 input ranges from 2.0000 mA with 0.1 µA resolution to 5.000 A with 1 mA resolution. The AC voltage input models may be set to one of 6 input ranges from 200.00 V with 10 µV resolution to 600.0 V with 0.1 V resolution.
The PM-DC Process Meters are ideal for indicating current or voltage output from process sensors, transmitters and transducers in applications involving temperature, pressure, level, flow rate, speed, humidity, level, distance and a myriad more. The PM-DC’s are also commonly used to detect DC power output from solar cells, power supplies, batteries as well as current consumption of DC powered motors and similar devices.
The PM-RM True RMS Meters are ideal for AC loads found in applications like electrical motors which will only operate properly if the AC line voltage and frequency are within the motor’s specified tolerances. If the thresholds specified by the motor manufacturer are exceeded, permanent damage to the motor as well as plant equipment could occur. Drops in line voltage or frequency may indicate an excessive load and the possibility of equipment malfunction. In these situations, the PM-RM meters are a simple means to monitor AC power lines and provide an alarm of non-compliance.
