AUTONICS VACUUM GAUGE
ZERO ADJUSTMENT: The AUTONICS PSA-V01 vacuum gage comes preset from the factory reading vacuum in
inhg and automatically runs in sensing mode when powered on. Do to different altitudes the gage may need to be
zeroed. Without pressure applied and vacuum door open exposing the gauge to atmospheric pressure it should read
0.0. If not zero the gauge by pressing and holding both up and down arrows simultaneously until the display reads
zero than release the buttons and it should return to sensing mode automatically and read zero.
SETTING OUTPUTS: The vacuum gauge comes with two outputs. These outputs are not used and are not hooked
up to do anything. The gauge is used to indicate vacuum only. To set the outputs so the LED light indicator will not
activate on the gauge press the mode key (M) once and the display should flash between ST1 and a value. Press the
up arrow until the display reads HI and then press the mode key (M) once and the display should flash between ST1
and a value. Press the up arrow key until the display reads HI and then press the mode key (M) once to return to
sensing mode.
CHANGING VACUUM SCALES: The vacuum gauge can be set for several different units of vacuum. Below is a list
of the different units of vacuum that can be chosen from. And there corresponding display code.

To change the units of vacuum press and hold the mode (M) button for three seconds or until the display flashes
between unit and vacuum unit scale code. Press the up or down arrow to change the vacuum unit scale code. To exit
