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 Double Click 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 250Ω

HART resistor active in the loop.

Connect the red input lead (+) of the PIE 820-ELITE 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 0.00 mA

(-25.0%) 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 820-ELITE 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.
