Safety information
This multimeter has been designed according to IEC −1010 concerning electronic measuring instruments
with an overvoltage category (CAT II) and pollution 2.
Follow all safety and operating instructions to ensure that the meter is used safely and is kept in good
operating condition.
Full compliance with safety standards can be guaranteed only with test leads supplied. If necessary,
they must be replaced with the type specified in this manual.
Safety Symbols
Important safety information, refer to the operating manual.
Dangerous voltage may be present.
Earth ground.
Double insulation (Protection class II).
Fuse must be replaced with rating specified in the manual.
Maintenance
• Before opening the case, always disconnect test leads from all energized circuits.
• For continue protection against fire; replace fuse only with the specified voltage and current ratings:
F 200mA/250V(Quick Acting)
• Never use the meter unless the back cover is in place and fastened completely.
• Do not use abrasives or solvents on the meter. To clean it using a damp cloth and mild detergent only.
During-use
• Never exceed the protection limit values indicated in specifications for each range of measurement.
• When the meter is linked to measurement circuit, do not touch unused terminals.
• Never use the meter to measure voltages that might exceed 600V above earth ground in category II installations.
• When the value scale to be measured is unknown beforehand, set the range selector at the highest position.
• Before rotating the range selector to change functions, disconnect test leads from the circuit under test.
• When carrying out measurements on TV or switching power circuits always remember that there may be high
amplitude voltages pulses at test points, which can damage the meter.
• Always is careful when working with voltages above 60V dc or 30V ac rms. Keep fingers behind the probe
barriers while measuring.
• Before attempting to insert transistors for testing, always be sure that test leads have been disconnected
from any measurement circuits.
• Components should not be connected to the hFE socket when making voltage measurements with test leads.
• Never perform resistance measurements on live circuits.
General description
The meter is a handheld 31/2 digital multimeter for measuring DC
and AC voltage, DC current, Resistance, Diode and Transistor with
battery operated.
Front-Panel
