1.2 Safety / Proper Usage
Caution!
Note the force gauge’s capacity before use and ensure that the capacity is not exceeded.
Producing a force greater than 200% of the gauge’s capacity can damage the internal load cell. An
overload can occur whether the gauge is powered on or off.
Typical materials suitable for testing 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 testing. 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 the
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.
Caution!
Do not use chargers or batteries other than supplied or instrument damage may occur.
If the AC adapter is plugged in, an 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 five-step process:
1. When battery life is greater than 75%, the following indicator is present:
2. When battery life is between 50% and 75%, the following indicator is present:
3. When battery life is between 25% and 50%, the following indicator is present:
4. When battery life is less than 25%, the following indicator is present:
5. When battery life drops to approximately 2%, the indicator from step 4 will be flashing.
Several minutes after (timing depends on usage and whether the backlight is turned on or off), a
message appears, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. An audio tone will
sound and the gauge will power off.
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, it can be accessed by separating the two halves of the gauge. Refer
to the Setup section for details.

3 SETUP
3.1 Mechanical Setup
3.1.1 Loading shaft orientation
In order to accommodate a variety of testing requirements, the orientation of the loading shaft may be set
up in either of the two positions shown below. In order to change the loading shaft orientation, loosen the
two captive screws on the back side of the housing, separate the two housing halves, rotate one half 180
degrees, and reassemble. Contact between the two halves is made by spring pins and contact pads on
the printed circuit boards.
Load cell shaft up Load cell shaft down
3.1.2 Mounting to a plate
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 withstand the load 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 be used for load bearing purposes. Failure to use a
dowel pin properly can result in a hazardous situation.

3.1.3 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. 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 operator and others in the vicinity. If using a grip or fixture from a
supplier other than Mark-10, ensure that it is constructed of suitably rugged materials and components.
Do not use jam nuts or tools to tighten grips or attachments onto the shaft. Finger-tighten only.
3.2 Installing the USB driver
If communicating via USB, install the USB driver available at:
Caution!
Install the USB driver before physically connecting the gauge to a PC with the USB cable.
Further instructions for configuring and using the gauge’s outputs are provided in the Communications
and Outputs section.

DIGITAL FILTERS
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 appears as follows:
(1 = Fastest)

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 memory of the instrument and the primary 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 appears as follows:
Upper Disabled
* Upper Enabled
5.000 Lower Disabled * Lower Enabled
Either one, two, or none of the set points may be enabled. To toggle between the tension and
compression directions, press the DIRECTION key.
If two set points have been enabled, they are displayed in the upper left corner of the display. If only one
set point has been enabled, the word “OFF” appears in place of the value. If no set points have been
enabled, the upper left corner of the display will be blank.
When set points are enabled, the following indicators are shown to the left of the primary reading:
Note: Set point indicators and outputs reference the displayed reading, not necessarily the current live
load.
– the displayed value is greater than the upper
force limit (NO GO HIGH)
– the displayed value is between the limits (GO)
– the displayed value is less than the lower force
limit (NO GO LOW)

7.3 Set Points Outputs Schematic Diagram
7.4 Using Set Points to Control a Mark-10 Test Stand
When using set points to stop/cycle Mark-10 motorized test stands, the upper and lower set points must
be set to opposite measuring directions. Both set points must be set, even if the intended application is
to stop/cycle at only one of the set points. The opposite set point should be a value sufficiently large that it
does not get triggered during the course of the test.
For certain Mark-10 test stands, the upper and lower set point directions are reversed.

Note: To achieve the accuracy specification of ±0.2%, it is recommended to calibrate the gauge at
5 or more even increments in both tension and compression directions. For example, a gauge with
capacity of 10 lbF should be calibrated at 2, 4, 6, 8, and 10 lb loads in each direction.
