Safety Considerations
General
This product and related documentation must be reviewed for familiarisation
before operation. If the equipment is used in a manner not specified by the
manufacturer, the protection provided by the instrument may be impaired.
Before Applying Power
Verify that the product is set to match the available line voltage and the correct
fuse is installed.
Before Cleaning
Disconnect the product from operating power before cleaning.
WARNING
Bodily injury or death may result from failure to heed a warning.
Do not proceed beyond a warning until the indicated conditions are
fully understood and met.
CAUTION
Damage to equipment, or incorrect measurement data, may result
from failure to heed a caution. Do not proceed beyond a caution
until the indicated conditions are fully understood and met.
This equipment must be earthed
An uninterruptible safety earth ground must be maintained from the mains power
source to the product’s ground circuitry.
WARNING
When measuring power line signals, be extremely careful and use a
step down isolation transformer whose output is compatible with
the input measurement capabilities of this product. The product’s
front and rear panels are typically at earth ground. Thus, never try
to measure AC power line signals without an isolation transformer.
WARNING
Instructions for adjustments when covers are removed and for
servicing are for use by service-trained personnel only. To avoid
dangerous electrical shock, do not perform such adjustments or
servicing unless qualified to do so.
