1.4 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.
The gauge is intended for use in muscle strength measurement, job task analysis, ergonomic
assessment, and related applications. Do not use the gauge to engage any 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.
USB connector
Power input jack
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:
Battery Life:
Indicator:
>75%
50 – 75%
25 – 50%
<25%
<2%
(flashing)
At a critically low level, 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 removing the battery cover in the rear of the
housing with two screws, as shown below:
