Mastech MS2030 Manual

1.Introduction
Make sure to read and follow all safety procedures to avoid
electric shock and/or injury.
The MS2030 is a safe, reliable, yet small handheld 3 ½ digit
digital clamp meter. Capable of measuring AC current, AC/DC
voltage, resistance, diode's forward voltage drop, and
continuity, it's ideal for both home users and
professionals.
2. Safety Instructions
The MS2030 meets EN61010-1
testing instruments and handheld digital multimeters. It's
designed to comply with EN61010-1
rating and pollution degree of 2.
All safety guidelines outlined should be followed otherwise

the protection provided by the instrument may be impaired.
Warning symbols in the manual alert users of potential

dangerous situations.
Precautions are to prevent the user from damaging the

instrument or the test object.
2.1 Precautions
To avoid possible electric shock, personal injury or damage to the
meter, please observe the following:
1. Before using the meter, check the meter for damage during
transport.
2. Check the test leads for damage to the insulation or wires
before use.
3. Ensure the meter works properly by testing a known voltage
first. If not working properly, have the meter serviced before
using.
4. Never exceed the protection limit values indicated
in the specifications for each range of measurement.
5. Always use caution when making voltage measurements
above 60V dc or 30V ac rms.
6. Make sure to use the correct input jack, function and range
when measuring.
7. Do not place the meter in any environment with dust, explosive
gas or vapor.
8. Always keep fingers behind the probe barriers.
9. Connect the common test lead first, then the hot lead.
Disconnect in reverse order.
10. Turn off power and discharge capacitors before measuring
resistance, diodes or continuity.
11. Failure to follow safety guidelines may prevent the meter's
built in protection from working properly.
12. To avoid damage or incorrect readings, check for AC voltage
present before making DC voltage measurements.

13. Do not use the meter with the battery cover not securely in
place.
14. When the " " symbol appears, replace the batteries to
avoid incorrect readings
15. Before opening the case, always disconnect test
leads from all energized circuits.
16. Only use the test leads provided with the meter. Replace
only with similar leads with matching specifications.
17. Do not touch input jacks during measurement to avoid electric
shock.
18. Before switching functions, remove test leads from an circuit.
