Model PD690 Universal Process Meter
Instruction Manual
Select Input Signal
The meter can be programmed to accept current or voltage input
using the Signal Input Selection Array. This jumper array is located at
the rear of the instrument, next to the screw terminal block. Remove
jumper J3 (if installed) to disable Lockout feature.
Table 1: Signal Input Selection Array
Initial Calibration with External Source (If Needed)
Initial calibration is required only when the
I-[AL
feature is to be
used with an input other than the default input of 4-20 mA. For best
results, allow the meter to warm up for at least 30 minutes.
1. Program the Signal Input Selection Array for desired input per
Table 1 above.
2. Apply power with
ENTER
and
ACK
buttons pushed. Release when
display stops flashing.
3. The meter scrolls through the choices
20, 5,
and
10.
Which
corresponds to input signals of 4-20 mA, 0-5 V or 1-5 V, and 0-10 V.
Push
ENTER
when desired value appears.
4. The meter flashes
InPt 1
. Apply low end signal, (4 mA or 0 V)*,
push
ENTER
.
5. The meter flashes
InPt 2
. Apply high end signal, (20 mA, 5 V,
10 V), push
ENTER
.
6. This completes the Initial Calibration and initializes INPUT 1 and
INPUT 2 scaling points to 4.000 & 20.000 mA, 0.000 & 5.000 V, or
0.000 & 10.000 V.
7. Refer to
I-[AL
scaling below for further instructions.
*For 1-5 V input signals, calibrate the meter with input1=0 V,
input 2=5 V.
