mA MODE
- pressing the knob will cycle through
READ
,
PWRM
,
READ%
,
PWRM%
and
OFF
.
READ
turns on the mA display and indicates current passing
through the loop proportional to the input of the transmitter
which is controlled by the output of the 525Plus. Choose
READ%
to display in percent of 4-20 milliamps.
PWRM
is POWER MEASURE which uses the internal loop
supply of the 525Plus to power up the transmitter while
indicating the current passing through the loop proportional to
the input of transmitter which is controlled by the output of the
525Plus. Choose
PWRM%
to display in percent of 4-20
milliamps.
If
PWRM
or
PWRM%
is selected an additional menu
selection of
LEAK DETECT
will appear. When
LEAK
DETECT
is turned on the 525Plus will display
LEAK
and
the amount of current that is uncontrolled in the loop. This may
be due to a faulty transmitter, corrosion causing a bridge to
ground or moisture present at some connection point. When
LEAK DETECT
tests a loop with leakage the loop mA
signal will be affected.
HART 250
Ω
- turn on the 250
Ω
resistor if you are powering
up a HART transmitter. This provides the loop load required for
HART communication.
