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
The CL532 has all the features of
the CL530, plus it will read up to
30 Vdc and source up to 24 Vdc.
SPECIFICATIONS Accuracy: ±0.012% rdg + 0.004 mA Temperature Effect: ±50 ppm/°C Operating Temperature Range: -20 to 60°C (-5 to 140°F) Storage Temperature Range: -30 to 60°C (-22 to 140°F) Relative Humidity Range: 10% ≤RH ≤90% [0 to 35°C (32 to 95°F)], non-condensing; 10% ≤RH ≤70% [35 to 60°C (95 to 140°F)], non-condensing Overvoltage Protection: 120 Vrms for 30 seconds, 240 Vrms for 15 seconds Overload Protection: 24 mA nominal Battery: 9V, alkaline (included) Battery Life: Source Mode: ≥18 hours at 12 mA (HartR disabled) Power Measure: 10 hours, read, 2 W limit sim. Read Vdc: >40 hours Loop Drive Ability: 1200 Ω at 20 mA for life of battery Loop Burden: <2V at 20 mA Loop Supply Limits (2 W Limit Sim.): 2 to 60 Vdc Connection: Alligator test leads attached, 610 mm (24") long Dimensions: 84 W x 180 H x 56 mm D (3.3 x 7.1 x 2.2") Weight: 326 g (11.5 oz) Source Current: Source 0 to 24 mA or -25 to 125% into ≤1200 Ω; a flashing HIGH Ω indicator appears if improperly connected 2-Wire Transmitter Simulate: Adjust loop current from 0 to 24 mA or -25 to 125% when powered by an external supply; LOW SUPPLY flashes to indicate a misconnection Power Measure: Power the loop and read 0 to 24 mA or -25 to 125%; CURRENT LIMITED flashes at >24 mA, protecting devices in the loop Read Current: Read 0 to 24 mA or -25 to 125%; CURRENT LIMITED flashes at >24 mA, protecting devices in the loop Read DC Voltage: Read 0 to 60 Vdc with 2x overrange ability and flashing OVERRANGE indicator 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%)
