mode, the gauge will turn itself off approximately 15
minutes after the last key is pressed.

Zero key:  This key performs a variety of functions.
If this key is pressed while the Pressure
Measurement mode is enabled, the current pressure
is stored as the “zero” value.  This value is then
subtracted from all subsequent display readings.
This value is retained even when gauge power is
turned off.
If this key is pressed immediately after pressing the
Reset key, the Factory “zero” value is recalled.
If this key is pressed while the Setup mode is
enabled, the Zero Key Enable feature will toggle on
and off.  If the Zero Key Enable feature is turned off
via the Setup mode, this key is disabled.

Peak/Valley key:  This key changes between
displaying the current pressure, the peak (HIGH)
recorded pressure value, and the valley (LOW)
recorded pressure value.  The appropriate legend
will be indicated on the display.
If this key is pressed immediately after pressing the
Reset key, the peak and valley pressure values are
cleared.  The peak/valley values are automatically
cleared each time the gauge is turned off.  To
continuously monitor pressure and peak/valley
readings, turn off the Battery Save feature.

Reset key:  This key is used in conjunction with the
Zero and Peak/Valley keys.

Units key:  This key scrolls through the list of
available engineering units.  The display will update
to indicate the selected units and the displayed
pressure value will be converted to the selected
engineering units.  If the selected engineering units
are not appropriate for the gauge’s range (i.e., mm
H
2O on a 0-5000 psi gauge), five dashes will appear
on the display.  The selected engineering unit will

voltage is low.  OVR will appear on the display instead
of the engineering units if the input pressure is outside
the range of the gauge.  ERROR will be displayed if the
input pressure is too large to be displayed (greater than
9999 counts).  If the selected engineering units are
inappropriate for the gauge’s range (i.e., mm H
2O on a
0-5000 psi gauge), “-----” will be displayed.
Replacing the Batteries
The Model 610 is powered by two 9V batteries.  When
battery voltage is low, BATTERY will be indicated on
the display.  To replace the batteries:
