Continue pressing to scroll the refrigerant list.

(See list of refrigerants on page 4.)

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.
