APPLICATION TIPS:
Allow the manifold to Zero at Turn-On:
The manifold displays will zero (CAL) each time the
manifold is turned on open to atmosphere. Zeroing the gauge
compensates the Pressure display for changes in (1) Altitude
and (2) Barometric pressure.
Pressure Calibration
Don’t be alarmed if your manifold gauge does not agree
with your mechanical gauges. The digital manifold is
calibrated with a very accurate pressure and is not affected
by vibration, motion or position.
Extending On-Time
The digital manifold will turn off automatically after 60
minutes to save battery life.
If any button is touched the digital manifold will stay on for
another 60 minutes.
Over/Under-Range Indicator
Pressures or temperatures below or above the rated
ranges will cause a “1” to be displayed.
Low Battery Indicator
Low batteries will be indicated by a blinking display.
Batteries For Low Temperature Applications
Using the gauge in a low temperature conditions will
shorten battery life. Change to the 9 volt Lithium battery
(Radio Shack 23-665) to solve this problem.
