Installation and Precautions
Install or remove gauge using wrench on hex
fitting only. Do not attempt to tighten by turning
housing or any other part of the gauge.
See label on back of gauge for range!
Use fittings appropriate for the pressure range of
the gauge.
Do not apply vacuum to gauges not specified for
vacuum operation. Permanent damage not
covered by warranty will result to the sensor.
Due to the hardness of 316 stainless steel, it is
recommended that a thread sealant be used to
ensure leak-free operation.
NEVER insert objects into the gauge port or blow
out with compressed air. Permanent damage not
covered by warranty will result to the sensor.
Absolute Reference Gauges
These models have engineering units shown on
the rear label such as PSIA, INHGA, INH2OA,
ZIN2A, BARA, MBARA, KPAA, TORR or TORRA,
MMHGA, KGCMA, ATMA. The “A” indicates
absolute reference. These ranges display
atmospheric pressure when the gauge port is
open to the atmosphere. They display zero at
high vacuum.
When the gauge port is open to the atmosphere,
it is normal for the reading to constantly change
in response to atmospheric pressure changes.
Do not adjust the calibration controls!
Operation – Ranges up to 1999
Press the round button on the front of the gauge
to activate the display. The gauge will stay on for
a period of time determined by the auto-shutoff
time. The gauge can be shut off at any time by
pressing the button again.
If the gauge was ordered without auto shutoff (-
NS) it will stay on until the button is pressed or
until the batteries are depleted. Turn gauge off
when not in use to conserve battery.
Display backlighting on BBL models is on
whenever the gauge is on. Backlighting may not
be apparent under bright lighting conditions.
Operation – Ranges 2000 and up
including 3000 psi, 5000 psi
These ranges have a 4-digit display with a lower
alphanumeric display. Press and hold the
pushbutton for approximately 1 second. The full-
scale range is indicated, display segments are
tested, and the reading and units are displayed.
Power-Up With One-Touch Zero –
Ranges 2000 and up including 3000 psi,
5000 psi
1. Make absolutely certain no pressure is applied
to the gauge. The gauge port should be
exposed to normal atmospheric pressure. Note
that the zeroing function may only be activated
at power-up and the stored zero correction is
erased when the gauge is shut off.
2. Press and hold the pushbutton.
3. The full-scale range is indicated and the
display segments are tested.
4. Continue to press the pushbutton until
oooooooo
is displayed and then release the button. This
indicates that the gauge has been zeroed.
5. The actual pressure is displayed.
Attempting to zero the gauge with pressure
greater than approximately 3% of full-scale
applied will result in an error condition, and the
display will alternately indicate
E
r r
0
and the
actual measured pressure. The gauge must be
powered down to reset the error condition.
Absolute reference gauges do not use the zero
feature since they read atmospheric pressure
under normal conditions.
Normal Operation – Ranges 2000 and up
including 3000 psi, 5000 psi
Following the start-up initialization, the display
indicates the pressure reading updated
approximately 3 times per second and the units.
The auto shutoff timer starts when the gauge is
powered up or whenever the button is pushed,
unless the gauge was ordered without an auto
shutoff time (-NS option).
If excessive vacuum is applied to a pressure-only
gauge, the display will indicate
–
E
r r
until the
vacuum is released. Applying vacuum to a gauge
designed for pressure may damage the pressure
sensor. If excessive pressure is applied (112.5%
over range), an out-of-range indication of
i
– – –
or
i
–.–.–.– will be displayed depending on
model.
Display Backlighting (BBL models only)
– Ranges 2000 and up including 3000
psi, 5000 psi
Display backlighting can be turned on by
momentarily pressing the button whenever the
gauge is on. The backlighting will turn on for one
minute and then automatically shut off. This also
restarts the auto shutoff timer. Backlighting may
not be apparent under bright lighting conditions.
Shut-Down – Ranges 2000 and up
including 3000 psi, 5000 psi
To shut off the gauge manually at any time, press
and hold the pushbutton until the display
indicates
O F F
and then release.
For gauges with auto shutoff, the display
indicates
O F F
five seconds prior to auto
shutoff. The pushbutton can be pressed to keep
the gauge on. The auto shutoff and backlight (if
equipped) timers are reset whenever the
pushbutton is pressed and released.
If the gauge was ordered without auto shutoff (-
NS option) it will stay on until manually shut off or
until the batteries are depleted. Turn gauge off
when not in use to conserve battery life.
Battery Replacement – All Models
A low battery indication will be shown in the
upper left-hand corner of the display when the
battery voltage falls sufficiently. The battery
should be replaced soon after the indicator
comes on or unreliable readings may result.
Remove the 6 Phillips head screws on the back
of the unit.
Carefully remove batteries from the holders by
lifting up the positive end of the battery (opposite
the spring). Take care not to bend or distort the
battery retention springs.
DO NOT discard the old battery into fire, any
other sources of extreme heat, or in any other
hazardous manner. Please consult local
authorities if there is any question about proper
disposal.
Always replace both batteries at the same time
with high quality alkaline batteries. Observe the
polarity of the batteries when replacing them. The
negative (flat) end of each battery should be
inserted first, and should face the spring in the
battery holder.
Replace the back cover, including the rubber
sealing gasket.
