CL530 Series
CL530, $725,
shown smaller
than actual
size. Test leads,
wrist strap and
9V battery
included.
EZ-Check Switch: Gives instant 
access to 4 and 20 mA or other 
user-set span limits; in read modes, 
the EZ-Check switch provides a 
max/min log of reading
EZ-Step Button: Allows one-handed 
stepping up and down the span in 6 
different step sizes
EZ-Dial Knob: Adjusts output by 
0.001 mA (0.01%); push and turn for 
100x faster adjustment—by 0.100 mA 
(1.00%)

The CL530 builds on OMEGA’s 
30 years of calibration experience. 
The user can check, calibrate, and 
troubleshoot 4 to 20 mA process 
control loops with this easy-to-use 
instrument.
The CL532 has all the features of 
the CL530, plus it will read up to 
30 Vdc and source up to 24 Vdc.
