Choose this function to measure from 0.000 to 24.000 milliamps
or -25.00 to 125.00%.
Move the power switch w to READ then Double Click the
EZ-DIAL knob to get into the Menu. Turn the knob e to scroll
through the settings and press the knob to make your selection.
Select mA for the FUNCTION and READ for the MODE. Choose
either mA or % and whether you need the 250
Ω HART resistor
active in the loop.
Connect the red input lead (+) of the PIE 830 to the more
positive point of the break and the black input to the more
negative point.
Signals below 0 mA or open circuits are indicated by 0.000 mA
(-25.00%) on the display. Signals above 24 mA are current
limited by protection circuitry with “OVERRANGE” flashed on the
display and the red OVERLOAD LED lit.
The PIE 830 measures the input signal and constantly updates
the display with the current reading. Move the EZ-CHECK switch
q to MAX to see the highest reading and to MIN to see the
lowest reading. Press and hold the knob e to clear the MAX and
MIN readings.
