destructive failure of a test sample is possible.

9. In aforementioned hazardous situations, it is strongly recommended that a machine guarding

system be employed to protect the operator and others in the vicinity from shards or debris.

10. Sensors have threaded holes or chucks, designed for the mounting of grips, fixtures, or

attachments. If any such accessories are used, ensure they are mounted firmly to prevent a

potential safety risk to the operator and others in the vicinity. If using an accessory from a supplier

other than Mark-10, ensure that it is constructed of suitably rugged materials and components.

Similar precautions should be taken when mounting the sensor to a test stand, work bench, or

other piece of equipment.

The 3i 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 indicator (refer to the illustration below). The battery will fully charge in approximately 8

hours.

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 indicator will power off.
