Xwsafety Information; Symbols Used In This Manual - Amprobe 33XR-A Manual De Uso

To avoid electric shock, personal injury, damage to the meter or the equipment
under test, adhere to the following practices:
•
The 33XR-A Digital Multimeter is UL, cUL, and EN61010-1 certified for
Installation Category III – 600V and Category II – 1000V. It is recommended for
use with local level power distribution, appliances, portable equipment, etc,
where only smaller transient overvoltages may occur, and not for primary
supply lines, overhead lines and cable systems.
•
Do not exceed the maximum overload limits per function (see specifications)
nor the limits marked on the instrument itself. Never apply more than
1000 V dc/750 V ac between the test lead and earth ground.
•
Inspect DMM, test leads and accessories before every use. Do not use any
damaged part.
•
Never ground yourself when taking measurements. Do not touch exposed
circuit elements or probe tips.
•
Do not operate the instrument in an explosive atmosphere.
•
Exercise extreme caution when measuring voltage >20 V // current >10 mA //
AC power line with inductive loads // AC power line during electrical storms //
current, when the fuse blows in a circuit with open circuit voltage >1000 V //
servicing CRT equipment.
•
Always measure current in series with the load – NEVER ACROSS a voltage
source. Check fuse first. Never replace a fuse with one of a different rating.
• Do not change the position of the Function/Range Switch while the MIN MAX,
HOLD, or REL feature is enabled. Erroneous readings will result.
•
Remove test leads before opening battery or case to change battery or fuses.
