mA SOURCE/ % SOURCE (Percent of 4 to 20 mA)
Choose this function to provide an output from 0.000 to 24.000
milliamps. The compliance voltage is a nominal 24 VDC to
provide the driving power to your milliamp receivers.
Move the power switch
w
to SOURCE then Double Click the
EZ-DIAL knob to get into the menu. Turn the knob to scroll
through the settings and press the knob to make your selection.
Select
mA
for the
FUNCTION
and
SOURCE
for the
MODE
.
Choose either
mA
or
%
and whether you need the 250
Ω
HART
resistor active in the loop.
Connect the output leads of the PIE 525Plus to the inputs of the
device being calibrated, making sure to check polarity. Red lead
to the plus (+) input and black lead to the minus (-) input.
Instantly output your SPAN and ZERO output settings by moving
the EZ-CHECK switch between HI and LO (defaults to 20 & 4
mA). You may also select any third output setting (such as
mid-range) using the SET position on the EZ-CHECK switch.
The output is adjusted in 0.001 mA (0.01%) increments by
turning the knob
e
. Press and turn the knob for faster dialing
with 0.100 mA (1.00%) increments.
Note: If there is a break in the loop (or no test leads are
connected)
ERROR
will be displayed and the mA value will blink.
