YourWheeler®DigitalTrigger Gauge comes fully assembled
and precisely calibrated from the factory. To use, simply
install 2 AAA batteries by following the steps below.
1. Locate and remove the Phillips head screw
holding the cover on the back side of the unit.
2. Once the cover is removed, place two AAA batteries
into the housing so that the negative side is against
the spring.
3. Replace t he cover and tighten the screw hand tight.
NOTE: Over tightening can damage the device.
The DigitalTrigger Gauge will automatically power off after
10 minutes of inactivity.
When the battery power in the device is low, a low battery
icon will display on the upper right corner of the screen.
When this appears,replace the batteries to ensure readings
are accurate.
Usage:
1. Once batteries are installed in the device, press the
button in the center to power it on. The screen
will light up and should display all zeros.
NOTE: Avoid applying any force to the sensor when
turning on the scale
2. Press the UNITS button to change between Pounds/
Ounces and Kilograms as desired.
3. Rotate the arm 180° out of the storage position until
it snaps into the upright position.
4. The arm may also be twisted 90 degrees to increase
clearance around some gunstocks. (PHOTO1)
NOTE: Always twist the arm back before folding.
Attempting to fold the arm in the twisted
position can permanently damage the product.

NOTE: The Digital Trigger Gauge was designed to
provide the most accurate reading possible
regardless of the position of the arm. By using
a ball joint, errors from pulling at a slight angle
can be minimized.
NOTE: The Digital Trigger Gauge
has a bladed trigger adapter to
allow its use with triggers that
have internal safety blades such
as: Glock®, Ruger®, Savage®
and other manufacturers.

The Digital Trigger Gauge has two function settings, Peak
and Live. Pressing the MODE button will switch between
these two as desired. The active mode will be displayed
after the rst zero on the LCD
Peak Function:
The peak function will hold the maximum force recorded
during each pull and calculate the maximum, minimum and
average pull weights. These calculations are performed
automatically and will constantly update and remain
in memory until the unit is powered off, or they can be
cleared by holding the DELETE button.
1. Press the MODE button until the word “PEAK” is
displayed
2. In the bottom left corner of the screen the text
“AVG” or “MAX” can be seen. Pressing MODE will
change the display to show the other values, but will
not clear the readings or calculations.
3. With all zeros displayed on the screen, cock the gun
and slowly pull the trigger until it trips.
TIP: Placing your trigger nger over the back side of
the sensor housing allows you to precisely
control the trigger pull. (PHOTO 4)
4. Pressing ENTER will accept the peak reading and enter
it into the calculations. Pressing DELETE will void the
readingand prevent it from being used in the calculations.
NOTE: Pressing and holding the DELETE button for 2
seconds will clear all calculations.
5. After pressing either ENTER or DELETE, the scale will
return to zero and be ready for a new reading. Simply
cock the gun again and repeat to get a new reading.
NOTE: The number of accepted readings is displayed as
N=XX in the bottom right corner.We recommend
using at least three to ve readings to get an
accurate value.
Live Function:
The live function provides a real-time reading of the sensor.
It will NOT hold a peak value.
1. Press MODE until the word “LIVE” is displayed after
the rst zero on the LCD screen.
2. Applying force on the sensor will show the live reading
at all times and will return to zero when the load is
removed.
NOTE: The Trigger Gauge has a maximum reading of
12.0lbs (5.45kg). Exceeding this force can cause
permanent damage to the sensor.
