FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to
human life and safety, and is capable of inflicting
personal injury.
If this instrument is to be powered from the AC line (mains) through an autotransformer,
ensure the common connector is connected to the neutral (earth pole) of the power
supply.
Before operating the unit, ensure the conductor (green wire) is connected to the ground
(earth) conductor of the power outlet. Do not use a two-conductor extension cord or a
three-prong/two-prong adapter. This will defeat the protective feature of the third
conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with
power applied and protective covers removed. Read the procedures and heed warnings
to avoid “live” circuit points.
Before operating this instrument:
1. Ensure the proper fuse is in place for the power source to operate.
2. Ensure all other devices connected to or in proximity to this instrument are properly grounded or
connected to the protective third-wire earth ground.
If the instrument:
- fails to operate satisfactorily
- shows visible damage
- has been stored under unfavorable conditions
- has sustained stress
Do not operate until performance is checked by qualified personnel.
