CL532 mA/Voltage Calibrator Loop Calibrator — 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)], no condensation; 10% ≤ RH ≤ 70% [35 to 60°C (95 to 140°F)], no condensation

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, reading, 2 W limit SIM card.

Read Vdc: > 40 hours

Loop drive capability: 1200 mA at 20 mA battery life

Loop load: <2 V loop compliance at 20 mA (2 W limit simulation): 2 to 60 Vdc

Connection: Alligator test leads, 610 mm (24") long

Dimensions: 84 W × 180 H × 56 mm D (3.3 × 7.1 × 2.2")

Weight: 326 g (11.5 oz)

Source current: Source 0 to 24 mA or -25 to 125%, ≤1200Ω; if connected incorrectly, a flashing HIGHΩ indicator appears

2-wire transmitter simulation: When powered by an external source, adjusts loop current to 0 to 24 mA or -25 to 125%; LOW SUPPLY flashes to indicate incorrect connection

Power measure: Powers the loop and reads 0 to 24 mA or -25 to 125%; CURRENT LIMITED flashes > 24 mA to protect equipment in the loop

Read current: Reads 0 to 24 mA or -25 to 125%; CURRENT LIMITED flashes > 24 mA to protect equipment

Read DC voltage: Reads 0 to 60 Vdc with 2× overrange capability and flashing overrange indicator

EZ-Check switch: Provides instant access to 4 and 20 mA or other user-set span limits; in read mode, the EZ-Check switch provides max/min reading memory

EZ-Step button: Allows one-handed stepping up/down through the span in 6 different step sizes

EZ-Dial knob: Output adjustment 0.001 mA (0.01%); push and turn for 100× faster speed — 0.100 mA (1.00%)

The CL530 includes test leads, operating manual, 9V alkaline battery, and NIST calibration certificate.
