Users manual
8 F1-F5 softkeys. Softkeys are used to select different menu options in digit multimeter menu.
Each softkey function is indicated by the label at screen bottom, and softkeys which are not
indicated by labels on the screen are invalid.
9 100mA and 12A input connection ends are used in AC and DC current measurement
10 Front/rear switch
Keys are classified into three main categories, that is, function key, setting key and redefine key,
among which function key is used to quickly select needed measurement function, setting key to
set system and function parameters, and redefine key to redefine by application program
according to changes of measurement functions.
Function key includes all the basic measurement function keys of DC voltage, DC current, AC
voltage, AC current, resistance 2-wire, resistance 4-wire, frequency, period, on-off, diode, sensor,
capacitance and ratio, among which resistance 2-wire and resistance 4-wire share one key,
frequency and period share one, and on-off and diode share one.
Setting key is to set parameters of current measurement function or system. Frequently-used
settings solely using one key is placed on the panel for quick setting; those non-frequently-used
settings are placed in general setting key and operated through menu. The frequently-used ones
include math function, trigger setting, holding, operating, single trigger, measurement setting,
etc.
Softkey includes 5 redefine keys to redefine by application program as required under different
functions.
