Series 2 Digital Force Gauges User’s Guide

Thank you…

Thank you for purchasing a Mark-10 Series 2 digital force gauge, designed
for tension and compression force testing applications from 2 to 100 lbF (10
to 500 N) full scale. The Series 2 is an essential component of a force
testing system, typically also comprising a test stand and grips.

With proper usage, we are confident that you will get many years of great
service with this product. Mark-10 force gauges are ruggedly built for many
years of service in laboratory and industrial environments.

This User’s Guide provides setup, safety, and operation instructions.
Dimensions and specifications are also provided. For additional information
or answers to your questions, please do not hesitate to contact us. Our
technical support and engineering teams are eager to assist you.

Before use, each person who is to use the Series 2 force gauge should
be fully trained in appropriate operation and safety procedures.

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
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

Caution!

Do not use AC adapters or batteries other than supplied or instrument damage may occur.

The gauge is powered either by a 9V non-rechargeable battery or by an AC adapter (input jack is located
in the left side of the housing).

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”, and the
gauge will then power off.

The gauge can be configured to automatically power off following a period of inactivity. Refer to the Other

Settings section for details.

Battery life is approximately 24 hours with the backlight on, or 92 hours with the backlight off. To change
the battery, loosen the two captive screws on the back side of the housing and separate the two housing
halves. A foam strip separates the battery from the PCB, as shown in the illustration below:

Ensure that the foam is positioned above the battery when reassembling the housing. Exercise care when
reassembling the two halves of the housing, ensuring that internal wires do not interfere.

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
oriented 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. Exercise care when reassembling the two halves of the housing,
ensuring that internal wires do not interfere.
