WARNING

1.Overview

To avoid electrical shock or personal injury,
please read all safety information,warnings and 
precautions before using the meter.

The MS8238C is a small, safe and reliable 3 ½ digit 
handheld auto ranging multimeter.This meter can 
measure AC/DC voltage, AC/DC current, resistance, 
diode, continuity, battery test, temperature and 
non-contact voltage tests.This tool is ideal for 
professionals and hobbyists alike.

Safety Information

2.1 Safety Standards

The MS8238C meets standards for CAT III 600V 
installations and a pollution degree of 2

.

• The protection provided by the meter can only be 
  ensured if all safety procedures are strictly followed.
• The safety symbols on the meter are to advise of 
  potential dangerous situations.Caution is required when 
  measuring close to the meter’s safety limits.
• Never exceed the protection limit values indicated in 
  the specifications for each range of measurement.

2.2 Precautions

• To avoid electrical shock or personal injury, observe and 
   follow all safety precautions
• Check the meter for damage before use.Do not use if 
   any damage is observed.
• Check the test leads for cracks or exposed wires before 
  using the meter.Replace if necessary.
• Ensure the meter works properly by testing a known 
  voltage source first.  If not working properly, the 
  protective equipment may be damaged; have the meter 
  serviced before using.
• Never measure voltages that may exceed the protection 
  limit indicated on the meter.
• Always be careful when working with voltages above 
  60V DC or 30V AC rms. Keep fingers behind the probe 
  barriers when making voltage measurements.
• Make sure the test leads are in the correct input jacks 
  before measurement.
• Do not expose the meter to explosive gas, dust or vapor.
• When connecting the test leads to a measurement 
  circuit, connect the common lead first, then the live lead.  
  Reverse when disconnecting.
• Turn off power to circuit and discharge all capacitors 
  before making resistance, continuity or diode 
  measurements.
• In order to avoid incorrect DC voltage readings, check 
  the circuit for AC voltage first, then put the meter in the 
  appropriate DC voltage range.
• Turn off circuit power and check fuses before connect 
  the leads when measuring current.Turn circuit power 
  on after making connection.
• Never use the meter unless the back cover is in place 
  and fastened securely.
