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 gauge 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
2
Page 4
Series 5 Digital Force Gauges User’s Guide
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 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
Power input jack
Serial connector
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 will appear, “BATTERY VOLTAGE TOO LOW. POWERING OFF”. A 4-tone
audio indicator 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, the battery may be accessed by separating the two halves of the
gauge. Refer to the Mechanical Setup section for details.

3 MECHANICAL SETUP
3.1 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 the spring pins and contact pads
on the printed circuit boards.
Load cell shaft up Load cell shaft down
3.2 Mounting to a plate
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 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
for load bearing purposes. Failure to use a dowel pin properly can result in a hazardous situation.
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
be used

Series 5 Digital Force Gauges User’s Guide
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

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 indicate 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.
Five operating modes are possible with Series 5 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.
5.4 Average Mode (AVG)
Average mode is used to obtain an average force reading over a specified period of time. Applications
include measurement of peel force, muscle strength, frictional force, and other tests requiring timeaveraged readings.
Before the parameters of Average Mode can be configured, it must be enabled. To do so, select Average
Mode from the menu, scroll to Enable and press ENTER. The display appears as follows:

primary reading.
At the completion of the averaging sequence, the peak values are retained until ZERO is pressed.
Another averaging sequence may be started after ZERO has been pressed. To exit Average mode, press
MODE and select the desired measuring mode.
5.5 External Trigger (ET)
This mode of operation is useful for measuring electrical contact activation force as well as
synchronization of multiple instruments for a “snapshot” view of applied forces. It is possible to capture
the reading with a normally open contact (high to low transition of the trigger signal) or a normally closed
contact (low to high transition).
Before the parameters of External Trigger Mode can be configured, it must be enabled. To do so, enter
the main menu, select External Trigger, scroll to one of the four available options and press ENTER.

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:

Page 11
Series 5 Digital Force Gauges User’s Guide
Available settings: 1,2,4,8,16,32,64,128,256,512,1024. It is recommended to keep the current reading
filter at its lowest value for best performance, and the displayed reading filter at its highest value for best
stability.
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 will appear as follows:
SET POINTS
Upper Disabled
* Upper Enabled
5.000
Lower Disabled
* Lower Enabled
3.500
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” will appear 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:
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)
10
Page 12
Series 5 Digital Force Gauges User’s Guide
Interactions with External Trigger Mode
Even if set points have been enabled, they are inactive when the gauge is in External Trigger
mode.
7.3 Using Set Points to Control Mark-10 Motorized Test Stands
When using set points to stop/cycle crosshead motion on a Mark-10 motorized test stand, both set points
must be enabled, and each set point must be set to opposite measurement directions. For example, if a
test requires the test stand to stop at 20 lb of compression force, set the upper set point to 20 lb
compression, and the lower set point to a tension value such as 10 lb, or any other value in the tension
compression that will not be triggered during the course of the test.
8 DATA MEMORY AND STATISTICS

10.1 Initial Physical Setup
The gauge should be mounted vertically to a test stand or fixture rugged enough to withstand a load
equal to the full capacity of the instrument. Certified deadweights or master load cells should be used,
along with appropriate mounting brackets and fixtures. Caution should be taken while handling such
equipment.

The gauge can be calibrated at up to 10 points in each direction. Enter the number of calibration
points for each direction (compression and tension). At least one point must be selected for each
direction.
Note: To achieve the accuracy specification of ±0.1%, it is recommended to calibrate the gauge
at 5 or more even increments in both the 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.
3. To escape the Calibration menu at any time, press ESCAPE. The display will appear as follows:
