1.4 MAINTENANCE
1.4.1 Please do not attempt to adjust or repair the meter by removing the rear case while voltage is being applied. A
technician who fully understands danger involved should only carry out such actions.
1.4.2 Before opening the case of the meter, always disconnect test leads from all sources of electric current.
1.4.3 To avoid the wrong reading causing electricity attack, when the meter displays“
”, you must change the
battery.
1.4.4 For continue protection against fire, replace fuse only with the specified voltage and current ratings: F
500mA/250V (quick acting).
1.4.5 Do not use abrasives or solvents on the meter; use a damp cloth and mild detergent only.
1.4.6 ALWAYS set the power switch to the OFF position when the meter is not in use.
1.4.7 If the meter is to be stored for a long period of time, the batteries should be removed to prevent damage to the
unit.
2. DESCRIPTION
- The 5 in 1 digital multi-tester has been designed to combine the functions of Sound Level Meter, Light Meter,
Humidity Meter, Temperature Meter and Digital Multimeter.
- The Sound Level function can be used to measure noise in factories, schools, offices, airports, home, etc.,
checking acoustics of studios, auditoriums and hi-fi installations.
- The Light function is used to measure illuminance in the field. It is fully cosine corrected for the angular incidence
of light. The light sensitive component used in the meter is a very stable, long life silicon diode.
- The Humidity/Temperature is for use a humidity semiconductor sensor and K type thermocouple.
- The digital Multimeter performs AC/DC Voltage, AC/DC Current, Resistance
，
Frequency, Duty, Capacitance
measurement and Continuity, Diode test.
- This meter is a portable professional measuring instrument with large LCD and back light easily reading. Single
operation of a range switch makes measurement convenient. Overload protection and low battery indication are
provided. It is an ideal multi-function Instrument with scores of practical applications for professional, workshop,
school, hobby and home use.
- When using, it can show ranges engineering unit enunciators measuring results.
- This meter has function of auto range and manual range.
- This meter has function of auto power off.
- This meter has function of data hold.
- This meter has function of relative measuring.
