EZ-CheckSwitch, Source Mode | Omega Engineering CL531 guide

EZ-Check™Switch

The EZ-Check™ switch has three positions -- high, dial, and low. Its position is shown at the left edge of the display with “HI” and “LO” indicators. Neither indicator indicates the middle position. Use of the EZ-Check™ switch depends on mode.

Source Modes:

Slide the EZ-Check™ switch to the HI and LO positions to recall the preset settings (Hi=20.00mA & Lo=4.00mA).

Hint: For faster calibrations, the position of the switch can be felt. This feature allows continuous monitoring of the device being calibrated without looking back at the CL531 display. This is also useful in poor lighting or under difficult operating conditions.

Read Modes:

In read mode, the CL531 calibrator records the maximum and minimum readings observed in each mode. Slide the EZ- Check™ switch to the Dial position to read the loop. Then Slide the EZ-Check™ switch to the HI and LO positions to display the max and min readings. Press EZ-Dial™knobto clear the readings. The display will flash “CLEARED” to confirm.

Source mode uses internal power to supply current from 0.00-24.00 mA into as much as 1200Ω until the end of battery life. The calibrator Graph will flash if connected improperly. The three-position EZ-Check switch provides instant preset 4mA at zero, 12mA at mid range and 20mA at full scale outputs. The output is adjusted in 0.01 or 0.10 mA increments (0.1 or 1.0) % display units with the EZ-Dial knob.

The CL531 can simulate a 2-wire transmitter in the 4-20 mA or % process loop. In source mode press the EZ-Dial™ Knob twice to get into the feature options. Then press the EZ-Dial™ Knob to select mA 2 – wire. The EZ-Check switch and EZ-Dial knob allow rapid and fine control of loop current.
