ELECTRICAL INSTALLATION
1. WIRING DIAGRAM
Depending on connector below :
2. CABLE+GROUND (26AWG, 6WIRE, SHIELD)
Shield may have to be connected to ground in
a high noise environment. Do not connect to
meter.
3. ZERO ADJUSTMENT
To compensate for pressure drift caused by
temp changes. At operating temperature with
no pressure on transducer, adjust the pressure
indicating device to read “0”
4. SPAN ADJUSTMENT
To calibrate readout device to transducer.
Press “CALIBRATE” and adjust reading to read
80% SPAN.

GENERAL OPERATION GUIDES
1. START UP
Before starting the extruder drive, ensure that the extruder is at operational temperature and plastic at tip is mol-
ten. A cold start can literally rip off the fragile diaphragm.
2. REMOVAL
Only remove transducer when barrel is at operational temperature and zero pressure.
Always clean hole of all solids before re-installing.
Check hole dimensions with thread gauge of cleaning kit to ensure proper hole. Hole size at tip can reduce over
time. Always remove transducer before cleaning inside barrel with abrasive cleaner or wire brush.
3. CLEANING TIP
Clean tip lightly with a dry cloth while tip is still hot.
Do not use any sharp tools (screwdriver, chisel, knife, wire brush etc.)
TROUBLE SHOOTING
1. Indicator Full Scale
2. Indicator Unstable Reading
3. Indicator Reads Only “0”
4. Indicates Wrong Pressure
