IMPORTANT SAFETY INFORMATION
Please read these instructions carefully before use and retain for future 

reference.

Important safety information. Read the instructions carefully.
High voltage. Danger.
Ground.
Double Insulation (Class II safety equipment).

Fuse must be replaced as per the specification herein.

!

200mA/250V

•  When using electrical appliances basic safety precautions should always 

be followed.

•  The instrument can only be used in conjunction with the probe, for the 

compliance with safety standards. If the probe needs replacing due 

to damage, the replacement must be of the same type or of the same 

electrical specifications.

• 

Do not exceed the input limits specified for each range.

•  When the instrument is measuring, do not touch the input terminal not in 

use.

•  When a measurement range is uncertain, turn the function/range switch to 

the maximum range position.

•  Before turning the function/range switch, make sure the probe is open with 

the circuit being measured.

•  Before on-line resistance measurement of voltage higher than 60V 

DC/30V AC, remember to keep your fingers behind the hand shield of the 

probe.

•  When measuring a TV set or switch power supply, watch for pulse in the 

circuit that may damage the multimeter.

•  Before measuring any transistor, make sure the probe is not connected to 

any circuit being measured.

•  Before taking the measurement of voltage with the probe, make sure there 

is no electronic element connected to the test socket of the transistor.

•  One Instruction manual

•  One pair of probes

•  One package

•  One 9V battery NEDA 1604 6F22

•  One K Thermocouple sensor (MAS838 only)

•  Rubber case (optional extra)
