1.2 Safety Information

Use this instrument only as specified in this manual. Otherwise, the protection
provided by the instrument may be impaired.

The following definitions apply to the terms “Warning” and “Caution”.

• “WARNING” identifies conditions and actions that may pose hazards to
the user.

• “CAUTION” identifies conditions and actions that may damage the in­strument being used.

1.2.1 WARNINGS

To avoid personal injury, follow these guidelines.

•

Before initial use, or after transport, or after storage in humid or semi-hu
mid environments, or anytime the instrument has not been energized for
more than 10 days, the instrument needs to be energized for a “dry-out”
period of 2 hours before it can be assumed to meet all of the safety re
quirements of the IEC 1010-1. If the product is wet or has been in a wet
environment, take necessary measures to remove moisture prior to apply
ing power such as storage in a low humidity temperature chamber operat
ing at 50 degree centigrade for 4 hours or more.

•

Use only a grounded AC mains supply of the appropriate voltage to
power the instrument. The dry-well requires a maximum of 1 amp, 50/60
Hz, 115/230 VAC (±10%).

•

DO NOT connect this unit to a non-grounded, non-polarized outlet.

•

DO use a ground fault interrupt device.

•

HIGH VOLTAGE is used in the operation of this equipment. SEVERE
INJURY or DEATH may result if personnel fail to observe safety pre

cautions. Before working inside the equipment, turn power off and dis
connect power cord.

2

DO NOT use this unit in environments other than those listed in the

•

user’s manual.

DO NOT use this unit for any application other than calibration work.

•

Follow all safety guidelines listed in the user’s manual.

•

Calibration Equipment should only be used by Trained Personnel.

•

1.2.2 CAUTIONS

To avoid possible damage to the instrument, follow these guidelines.

Operate the instrument in room temperatures between 5-50°C (41-122°F).

•

Allow sufficient air circulation by leaving at least 6 inches of space be
tween the instrument and nearby objects. Overhead clearance needs to al
low for safe and easy insertion and removal of probes for calibration.

The dry-well is a precision instrument. Although it has been designed for

•

optimum durability and trouble free operation, it must be handled with
care. The instrument should not be operated in excessively wet, oily,
dusty, or dirty environments. It is important to keep the wells of the in­strument clean and clear of any foreign matter. Do not operate near flam­mable materials.

• DO NOT use fluids to clean out the well.

• If a mains supply power fluctuation occurs, immediately turn off the in-

strument. Power bumps from brown-outs and black-outs could damage
the instrument. Wait until the power has stabilized before re-energizing
the instrument.
