Operating Instructions
READ mA, READ % (Percent of 4 to 20 mA)
Choose this function to measure from 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 250
Ω
HART
resistor active in the loop.
Connect the red input lead from jack (5) of the 830PM to the more positive point
of the break and the black input lead from jack (6) 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
“OVER RANGE” on the display and the red OVERLOAD LED lit.
The 830PM 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.
