To ensure safe operation and service of the
meter, follow these instructions.Failure to
observe warnings can result in severe Injury.
Warning
Identify hazardous conditions and actions that
could cause BODILY HARM or DEATH
-Individual protective equipment should be used
if HAZARDOUS LIVE parts in the installation
where measurement is to be carried out could
Be ACCESSIBLE.
-If the equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
-To reduce the risk of fire or electric shock, do
not expose this product to rain or moisture.
-Verify the Meter operation by measuring a
known Current. If in doubt, have the Meter
serviced.
-Do not apply more than the rated voltage/
Current, as marked on Meter.
-To avoid false readings that can lead to electric
shock and injury, replace battery as soon as low
battery indicator.
- Do not use Meter around explosive gas or
vapor.
