Caution!
Note the force gauge’s capacity before use and ensure that the capacity is not exceeded.
Producing a force greater than 150% of the gauge’s capacity can damage the internal load cell. An
overload can occur whether the gau g e is powered on or off.
Typical materials able to be tested include many manufactured items, such as springs, electronic
components, fasteners, caps, films, mechanical assemblies, and many others. Items that should not be
used with the gauge include potentially flammable substances or products, items that can shatter in an
unsafe manner, and any other components that can present an exceedingly hazardous situation when
acted upon by a force.
The following safety checks and procedures should be performed before and during operation:
1. Never operate the gauge if there is any visible damage to the AC adapter or the gauge itself.
2. Ensure that the gauge is kept away from water or any other electrically conductive liquids at all
times.
3. The gauge should be serviced by a trained technician only. AC power must be disconnected and
the gauge must be powered off before the housing is opened.
4. Always consider the characteristics of the sample being tested before initiating a test. A risk
assessment should be carried out beforehand to ensure that all safety measures have been
addressed and implemented.
5. Wear eye and face protection when testing, especially when testing brittle samples that have the
potential to shatter under force. Be aware of the dangers posed by potential energy that can

accumulate in the sample during testi ng. Extra bodily protection should be worn if a destructive
failure of a test sample is possible.
6. In certain applications, such as the testing of brittle samples that can shatter, or other applications
that could lead to a hazardous situation, it is strongly recommended that a machine guarding
system be employed to protect the operator and others in the vicinity from shards or debris.
7. When the gauge is not in use, ensure that the power is turned off.
2 POWER
The gauge is powered either by an 8.4V NiMH rechargeable battery or by an AC adapter. Since these
batteries are subject to self discharge, it may be necessary to recharge the unit after a prolonged period
of storage. Plug the accompanying charger into the AC outlet and insert the charger plug into the
receptacle on the gauge (refer to the illustration below). The battery will fully charge in approximately 8
hours.
USB connector
Caution!
Do not use chargers or batteries other than specified or instrument damage may occur.
If the AC adapter is plugged in, a corresponding icon appears in the lower left corner of the display, as
follows:
If the AC adapter is not plugged in, battery power drainage is denoted in a three step process:
The gauge can be configured to automatically power off following a period of inactivity. Refer to the Other
Settings section for details.
If battery replacement is necessary, the battery may be accessed by separating the two halves of the
gauge. Refer to the Mechanical Setup section for details.
1. When battery life is greater than 30%, no indicator is present.
2. When battery life drops to approximatel y 30%, an indicator appears as follows:
3. When battery life drops to approximately 10%, the indicator will appear as follows:
4. When battery life drops to approximately 2%, the indicator from step 2 will be flashing.
Several minutes after (timing depends on usage and whether the backlight is turned on or
off), a message will appear, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone
audio indicator will sound and the gauge will power off.

Although the gauge may be used by hand, proper mounting is important if attached to a fixture or test
stand. The round steel insert with a hole in the back of the housing is provided to withs ta nd the loa d
during a test. A mating dowel pin should be used (see illustration below). Mounting plates on Mark-10 test
stands include a dowel pin and clearance holes for the four threaded holes located near the corners of
the housing. These holes are designed to accommodate screws in order to hold the gauge in place
(Mark-10 test stands include a set of thumb screws for gauge mounting). The screws must not

3.3 Mounting attachments to the gauge
The force gauge’s threaded loading shaft is designed to accommodate common grips and attachments
with female mounting holes. To mount a grip, gently thread it onto the shaft. Other mounting adapters are
also available to prevent rotation. Ensure that the grip or fixture is positioned to ensure axial load with
respect to the loading shaft of the force gauge. When using a grip, ensure that it secures the sample in
such a way that it is prevented from slipping out during a test, preventing a potential safety risk to the

5 OPERATING MODES
Caution!
In any operating mode, if the capacity of the instrument has been exceeded by more than 110%,
the display will show “OVER” to indic ate an overload. A continuous audible tone will be sounded
until the MENU key has been pressed or the load has been reduced to a safe level.
Three operating modes are possible with Series 4 gauges. To cycle between the modes, press MODE
while in the home screen.
5.1 Real time (RT)
The primary reading corresponds to the live measured reading.
5.2 Peak Compression (PC)
The primary reading corresponds to the peak compression reading observed. If the actual force
decreases from the peak value, the peak will still be retained in the primary reading area of the display.
Pressing ZERO will reset the value.
5.3 Peak Tension (PT)
Same as Peak Compression, but for tension readings.
6 DIGITAL FILTERS
Digital filters are provided to help smooth out the readings in situations where there is mechanical
interference in the work area or test sample. These filters utilize the moving average technique in which
consecutive readings are pushed through a buffer and the displayed reading is the average of the buffer
contents. By varying the length of the buffer, a variable smoothing effect can be achieved. The selection
of 1 will disable the filter since the average of a single value is the value itself.
To access digital filter settings, select Filters from the menu. The display will appear as follows:

7 SET POINTS
7.1 General Information
Set points are useful for tolerance checking (pass/fail),
triggering an external device such as a motorized test
stand, or alarm indication in process control applications.
Two limits, high and low, are specified and stored in the
non-volatile memor y of the instrum ent and the prim ary
reading is compared to these limits. The results of the
comparisons are indicated through the three outputs
provided on the 15-pin connector, thus providing “under”,
“in range”, and “over” signaling. These outputs can be
connected to indicators, buzzers, or relays as required
for the application.
7.2 Configuration
To configure set points, select Set Points from the menu. The screen will appear as follows:
Upper Disabled
* Upper Enabled
5.000 Lower Disabled * Lower Enabled
