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.

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.
