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.
Caution!
Do not use chargers or batteries other than specified or instrument damage may occur.
If the AC adapter is plugged in, a corresponding 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 three step process:
1. When battery life is greater than 30%, no indicator is present.
2. When battery life drops to approximately 30%, an indicator appears as follows:
3. When battery life drops to approximately 10%, the indicator will appear as follows:
4. When battery life drops to approximately 2%, the indicator from step 2 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.
