Technical Specifications
Accuracy: ±0.1mm/±0.004"
Resolution: 0.05mm/0.002"
Working Range: Scale: 0~80mm/0"~3"; Needle: 0~50mm/0"~2"
Power Supply: One CR2032 3V button cell (included)
Working temperature: 32°F to 122°F/0°C to 50°C
Working humidity: ≤85%
Button Locations and Functions (Fig. 1)
ON/OFF: Short single press turns Gauge on in Absolute
Mode (see below for explanation of modes). A second short
press sets the digital readout to 0.
Mm/Inch/Fraction: Short press switches between the three
units of measure. In Fraction mode, the Gauge displays to
the nearest 1/32"; a flashing “in.” indicates that the gauge is
rounding off the measurement.
INC/ABS: Short press switches between Absolute and
Incremental Modes.

Installing/Changing the Battery
1. Pull up on the tab on the top of the digital readout to
remove the battery holder. Fig. 1.
2. Remove the old battery and install a new one, making
sure that the side marked “+” faces down.
3. Carefully slide the battery holder back into the top of the
digital readout. Do not tilt or twist.

Zeroing out the Gauge
1. Loosen the thumbscrew on the right side of the digital
indicator (if necessary).
2. Position the Digital Height Gauge so its feet are flat
on a flat surface. Lower the center rule until it touches
the surface.
3. Press the “ON/OFF” button once to turn on the Gauge.
Press it a second time and hold for a second to set the
Gauge to 0.
4. Press the “mm/inch/fraction” button to select the desired
unit of measure.
5. The Gauge is now calibrated, and the digital readout will
show the distance the rule is moved.
6. To set the Gauge for use, lift the center rule to the desired
height and tighten the thumbscrew to lock in the setting.
Do not overtighten the thumbscrew.
Absolute and Incremental Modes
The Digital Height Gauge has two operational modes:
Absolute (ABS) and Incremental (INC). In Absolute Mode
(the default), once the Gauge is zeroed out, any movement of
the center rule from the zero position is shown on the digital
readout.
In Incremental Mode, the Gauge can be set to display the
distance between the first setting and the next setting – for
example, if you want to rout a 1/4" deep groove in a board at
a router table in two passes. To do this, you would zero out

the Gauge in ABS mode; then move the center rule up to 1/8"
and push the “INC/ABS” button to switch to Incremental
Mode. The digital indicator will switch to “0”. Tighten the
thumbscrew to secure the setting, set the bit height and make
the first pass. Now loosen the thumbscrew and slide the
rule until the digital readout displays 1/8" again. Tighten the
thumbscrew and use the Gauge to set the bit height for the
second pass – reaching a total depth of 1/4".
Using the Extension
The Digital Height Gauge comes with an extension that
stores on one of the gauge’s legs. It clips onto the bottom of
the center rule to provide an additional 2" measuring capacity
below the guide, especially useful if measuring the depth of a
dado or mortise.

Installing/Changing the Battery

Operating Instructions
Turn the knob next to the digital
readout to control the tension for opening and closing
the Digital Angle Rule. Rotate clockwise to tighten and
counterclockwise to loosen. The Digital Angle Rule
can be zeroed out in two different ways – fully closed
or fully open – depending on whether you want to
measure the acute or obtuse angle.
To measure the angle from the left: Turn the device on
and place it on edge on the surface in the closed position.
Press the “0/ON” button to set the readout to 0. Keeping the
rule with the digital readout anchored on the surface, rotate
the other rule to the angled surface to determine the angle.
To measure the angle from the right: Turn the device on
and place it on edge on the surface in the open position. Press
the “0/ON” button to set the readout to 0. Keeping the rule
with the digital readout anchored on the surface, rotate the
other rule to the angled surface to determine the angle.
