Safety Information
A Warning identifies conditions and procedures that are dangerous to the user.
A Caution identifies conditions and procedures that can cause damage to the
Product or the equipment under test.
 Warning
To prevent possible electrical shock, fire, or personal injury:
•
Only assemble and operate high-pressure systems if you
know the correct safety procedures. High-pressure liquids
and gases are hazardous and the energy from them can be
released without warning.
•
Read all safety information before you use the Product.
•
Carefully read all instructions.
•
Do not use the Product around explosive gas or vapor.
•
Use the correct terminals, function, and range for
measurements.
•
Do not apply more than the rated voltage, between the
terminals or between each terminal and earth ground.
•
Do not touch voltages >30 V ac rms, 42 V ac peak, or
60 V dc.
•
Remove all probes, test leads, and accessories before the
battery door is opened.
•
Do not exceed the Measurement Category (CAT) rating of
the lowest rated individual component of a Product, probe,
or accessory.
•
Disable the Product if it is damaged.
•
Do not use the Product if it is damaged.
•
Remove the input signals before you clean the Product.
•
Use only specified replacement parts.
•
Have an approved technician repair the Product.
•
Use the Product only as specified, or the protection
supplied by the Product can be compromised.
•
Pressure sensors can be damaged and/or personnel injury
can occur due to improper application of pressure. Vacuum
should not be applied to any gauge pressure sensor. The
Product display shows “OL” when an inappropriate
pressure is applied. If “OL” is shown on any pressure
display, the pressure should be reduced or vented
immediately to prevent Product damage or possible
personnel injury. “OL” is shown when the pressure exceeds
110 % of the nominal range of the sensor or when a vacuum
in excess of 2 PSI is applied on gauge range sensors.
