SAFETY NOTES
• Do not exceed the maximum allowable input range of any function.
• Do not apply voltage to meter when resistance function is selected.
• Set the function switch OFF when the meter
• Remove the battery if meter is to be stored for longer than 60 days.
WARNINGS
Set function switch to the appropriate position before measuring.
•
When measuring volts do not switch to current/resistance modes.

CAUTIONS
Improper use of this meter can cause damage, shock, injury or death. Read and
•
understand this user manual before operating the meter.
Always removethe test leads before replacing the battery or fuses.
•
Inspect the condition of the test leads and the meter itself for any damage before
•
operating the meter. Repair or replace any damage before use.
IJsegreatcare whenmakingmeasurements if thevoltagesaregreaterthan 25VAC
rms or 35VDC. These voltages are considered a shock hazard.
Always discharge capacitors and remove power from the device under test before
•
performing Diode, Resistance or Continuity tests.
Voltage checks on electrical outlets can be difficult and misleading because of the
•
uncertainty Of connection to the recessed electrical contacts. Other means should be
used to ensure that the terminals are not "live".
If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
This device is not a toy and must not reach children's hands. It contains hazardous
•
objects as well as small parts that the children could swallow. In case a child swallows
any of them, please contact a physician immediately
Do not leave batteries and packing material lying around unattended;they can be
dangerous for children if they use them as toys
In case the device is going to be unused for an extended period of time, remove the
•
batteries to prevent them frorn training
Expired or damaged batteries can cause cauterization on contact with the skin. Always,
•
therefore, use suitable hand gloves in such cases
See that the batteries are not short-circuited.
•
Do not directly view or direct the laser pointer at an eye. Low power visible lasers
•
do not normally present a hazard, but may present some potential for hazard if viewed
directly for extended periods of time
