CM-Series
The CM-35XT is specially designed to simplify installation, calibration and scaling. It is one of the CM-Series family of meters.
Deriving their operating power from the current loop, these meters require no external power supply. The CM-35XT is a functional replacement for the now obsoleted CM-35X meter. Its counterpart, the CM-35XTL, has the same pinout as the CM35XT but requires only a 1.0V loop drop to operate, making it particularly suitable for current loops that would otherwise exceed their power supply capacity with too many devices connected.
The meters feature Display Hold, Display Test and AutoPolarity Indication. The polarity indication may be disabled or reversed by repositioning jumper clips on internal header pins.
Another feature of the CM-series meters is the 41/2 digit LCD display which provides for a non-active trailing dummy zero or a C/F descriptor. Descriptor indication may be disabled or re-programmed by repositioning jumper clips on internal header pins.
Other devices can also be added to the loop.

The CM-Series is shipped in a standard Slim Bezel case. The Slim Bezel case is compatible with the TM, SM, PM, & SP Series of meters. The CM-Series can be ordered in End Mount cases for twin mounting or combinations of multiple center mount cases and two end mount cases for stack mounting.
