Yokogawa CL420 Clamp-On Process Meter for 4-20 mA current loops

Yokogawa’s CL420 Clamp-On Process Meter is designed to make checks on DC mA lines without breaking the circuit. This compact instrument is an effective troubleshooting tool for 4-20 mA current loops on flowmeters, field instrument transmitters, signal conditioners, distributors, valve positioners and meters, saving users time on site.

The CL420’s clamp has a relatively large hole that allows proper clamping around conductors up to 6 mm in diameter and ensures stable readings with an accuracy of 0.2% up to 20 mA. The backlit dual display provides both current value and percentage of range information along with battery condition.

Suitable for low-light situations, the meter incorporates an LED torchlight and illuminated panel keys. The unit has two input ranges, 0-20 mA and 0-100 mA, plus an analog DC mV output for use with a DMM, recorder or data logger. Other functionality includes an auto power-off feature and data hold.

The product comes with a soft carrying case plus batteries. Output cables with either banana plug or screw terminals are optionally available.
