1.Safety Information
1.1 Read the following safety information carefully before attempting to operate
or service the meter.
1.2 To avoid damages to the instrument do not exceed the maximum limited of
the input values show in the technical specification tables.
1.3 Never measure current while the test leads are inserted into the input jacks.
1.4 Do not use the meter or test lead if they look damaged, Use extreme
caution when working around bare conductors or bus bars.
1.5 Caution when working with voltage above 600 VDC or 450 VAC rms. Such
voltage pose a shock hazard.
2. Operating environments
AC Current : 0.01 A....400 A
AC Voltage : 1 V....450 V (AC)
DC Voltage : 1 V....600 V (DC)
The meter display is a liquid crystal assembly providing a readably display in
a light conditions. The decimal point is automatically positioned, and the polarity sign
(minus) is lighted for negative DC measurement (plus is undertook if no sign spears.)
so the the display is direct reading in units selected at the rotary switch. Over range
measurements are indicated by blanking all but the MSD, decimal point and polarity
sign (if negative). In addition the display included a low battery is indicated, Operator
should replace the used battery with new one.
