Tool Usage Instructions
A. High Pressure Gauge (TG-0200):
This pressure gauge is used for input fuel pressure readings. Connectivity depends entirely upon
your application. Do not connect the gauge where the delivery pressure will exceed 200 PSI.
B. Differential Pressure Test Gauges (TG-005 & TG-010):
•
Both the TG-005 (0-5 PSI) and the TG-010 (0-10” WC) are differential pressure gauges. This
means they can be used to measure the difference in pressures between two separate areas or
they can be used to measure either positive pressure or negative pressure (vacuum).
TG-005
TG-010
•
Before using either of the differential pressure test gauges, they should to be calibrated against a
manometer or a
known
calibrated gauge. To calibrate a gauge:
Remove the front cover by unscrewing it in a counter-clockwise direction. You may need to use
a pair of channel lock style pliers (be careful as the cover is made of plastic). DO NOT use any
clamping tool on the body of the gauge.
