F22BBL Backlight Time Selection
The lower display will indicate BL if the
display backlight is enabled or NO BL if
display backlight is disabled.
Use the s button to enable backlighting
and the t button to disable backlighting.
Press the power button to save the setting.
If NO BL was selected the user setup is
complete and the gauge will restart and be
ready for use with the new configuration.
If BL was selected the current backlight
auto shutoff time is displayed in minutes.
1 minute is the factory default.
Use the s and t buttons to select the
minutes for backlight shutoff time.
A setting of zero disables the auto shutoff timer and the backlight
will be on whenever the gauge is on. The maximum setting is 255
minutes. The gauge auto shutoff time will override the backlight
time. When the desired time is displayed, press and release the
power button to save your selection and restart the gauge.
F20B Memory—M4 Versions
The M4 version allows recording pressure readings of up to four
tires. While in the memory mode the peak reading is captured.
The number 1 is shown on the upper
display. The lower display will indicate the
label for memory 1.
Use the s and t buttons to select MEM 1,
or LF, RF, RR, or LR. The labels can be set
up in any order.
When the desired label for memory 1 is
displayed, press the Power button.
Repeat the steps for the other memory
locations. When the desired label for memory
4 is displayed, press and release the Power
button to save the user configuration and
restart the gauge.
F20B Memory—M8 Versions
The M8 version allows recording of up to eight pressure readings.
While in the memory mode the peak reading is captured.
The eight memory labels can be set for MEM
1 through MEM 8, or for 4 tires and 4 tire
inner liners used for auto racing.
After auto shutoff time selection, the number
1 is on the upper display. The lower display
will indicate the label for memory 1.
Use the s and t buttons to select MEM 1,
or one of the 8 memory labels: LF, LF IN, RF,
RF IN, RR, RR IN, LR, LR IN. The labels can
be set up in any order.
When the desired label for memory 1 is dis-
played, press and release the Power button.
Repeat the steps for the other memory
locations. When the desired label for the last
memory location is displayed, press and release the Power button
to save the user configuration and restart the gauge.
Battery Replacement
A low battery indication will be shown in the upper left-
hand corner of the display when the battery voltage falls
sufficiently. The batteries should be replaced soon after
the indicator comes on or unreliable readings may result.
1. Remove the 6 Phillips screws on the back of the unit.
2. Lift up the battery holder.
3. Remove batteries by lifting up the
positive end of the battery (oppo-
site the spring) taking care not to
bend the battery holder spring.
4. Discard old batteries properly,
do not discard into fire, sources
of extreme heat, or in any haz-
ardous manner.
5. Always replace both batteries at
the same time with high quality
alkaline batteries.
6. Install batteries with correct orientation. Incorrect polarity will
damage the gauge. The negative (flat) end of each battery
should be inserted first facing the battery holder spring.
7. Replace battery holder face down being careful not to pinch the wires.
8. Replace the back cover, including the rubber gasket and rein-
stall the six screws.

Calibration Preparation
Gauges are factory calibrated at approximately 23°C using NIST
traceable calibration equipment. Calibration is not required before
using the gauge. Calibration intervals depend on your quality stan-
BL
dards, but annual re-calibration is customary. Calibration should

t
The calibration system must be able to generate and measure
- or -
pressure/vacuum over the full range of the gauge and should be
at least four times more accurate than the gauge being calibrated.

A vacuum pump able to produce a vacuum of 100 microns (0.1 torr
or 100 millitorr) or lower is required for vacuum gauges.

s and t Button Operation
Each time one of the s or t buttons is pressed and released
quickly, a small change is made to the digitized pressure signal. It
may take more than one of these small changes to result in a single
digit change on the display.
To make larger changes, press and hold the appropriate button.
After about one second, the display will begin to change continu-
ously. Release the button to stop. Then make fine adjustments by
pressing and quickly releasing the buttons as previously described.
