CM-Series
The CM-35XTL is a functional replacement for the CM-35X meter, but requires only a 1 V loop drop to operate, making it especially suitable for current loops that would otherwise exceed their power supply capacity with too many devices connected. Its counterpart, the CM-35XT, is a lower-cost alternative to the CM-35XTL. It has the same pinout as the CM-35XTL but a higher loop drop of 6.5V, making it suitable for applications where fewer devices are in the current signal loop.
The meters feature Display Hold, Display Test and Auto-Polarity 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 4 1/2 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.
The CM-35XTL & CM-35XT are designed to be easily user scaled and calibrated to almost any conceivable engineering unit, such as temperature, pressure, viscosity or flow rates etc., without requiring component changes.
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.
