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
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

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:

Parameter Description
Initial Delay The time delay, in seconds, before the averaging sequence commences. Averaging Time The time duration, in seconds, of the averaging sequence. Trigger Force
The minimum force required to start the averaging sequence. Toggle between compression and tension directions by pressing the DIRECTION key. Initial delay follows the trigger force.
After the parameters have been configured and the menu has been exited, press MODE until AVG is displayed. Then press ZERO. Average mode is now armed, and the averaging sequence will commence when the trigger force has occurred. The current status of the average sequence is displayed below the primary reading, as follows:
Step Status Abbreviation Description
1 TRIG WAIT The trigger force has not yet occurred. 2 INIT DLY The initial delay is currently taking place. 3 AVERAGING The gauge is collecting readings. The status will be flashing until
averaging has been completed.
4 AVRG DONE Averaging has been completed. The average force is displayed in the
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. The options are as follows:

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:
DIGITAL FILTERS
(1 = Fastest)
Current Reading 1 Displayed Reading 1
Two filters are available:
Current Reading – Applies to the peak capture rate of the instrument.
Displayed Reading – Applies to the primary reading on the display.
9
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)
