Safety Precautions
The following general safety precautions must be observed during all phases of operation, service and repair of this
instrument. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety
standards of design, manufacture and intended use of the instrument. Vitrek Corporation assumes no liability for the
customer's failure to comply with these requirements.
GROUND THE INSTRUMENT
To minimize shock hazard, the instrument must be connected to an electrical ground. This should be accomplished through the
earth ground pin of the instrument's power connector and power cord.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE
Operation of any electrical instrument in the presence of flammable gases, fumes or particles constitutes a definite safety hazard.
DO NOT REMOVE COVERS
Operating personnel must not attempt component replacement or internal adjustment. Dangerous voltages may exist internally
even when the power is switched off. Because of the dangers of introducing additional hazards, do not install substitute parts or
perform any unauthorized modifications to the instrument. Refer the unit to qualified maintenance personnel or to your nearest
Vitrek service center.
DO NOT OPERATE ALONE
Do not attempt to operate the instrument at high voltages unless another person, capable of rendering first aid and resuscitation, is
present.
DANGER! HIGH VOLTAGE
Use extreme caution when working with high voltages. Never remove or insert test leads from the 944i while high voltage is
present. Only use test lead materials which have adequate high voltage ratings. Inspect test leads regularly for signs of wear and
abrasion.
READ AND UNDERSTAND THE MANUAL
Prior to operating this instrument, the user must be familiar with the operating procedures, controls and precautions.
