    How can I measure direct current strength using built-in 24 V power supply when operating AKTAKOM AM-7070 calibrator?

    1. Press power switch, turn on AKTAKOM AM-7070 calibrator
    2. Press input/output conversion key to enter measurement mode (you will see INPUT indicator on the display).
    3. Press mA/mA% conversion key, make it indicate mA or mA%.
    4. Connect the red test lead to +LOOP, the black one to mA jack.
