(8) SELECT key

When setting the rotary switch to a measurement function, the meter will enter its first

measurement mode, while pressing the SELECT key it is possible to select the second or the third

measurement mode. However, there is only one for the diode and Capacitance measurements.

(9) WAKE key

After the meter being automatically shutdown, by pressing the WAKE key it can be woken up to

resume the measurement. In case of pressing POWER switch(for putting on the unit) and WAKE key

simultaneously, the meter will in a continuously working state without the automatic shutdown

function.

simultaneously display the maximum value. By pressing this key again it will be possible to display

the minimum value and the maximum value-minimum value. When releasing the key after pressing

it for two seconds, the maximum and minimum record state will be exited. Pressing this key will be

void during frequency、diode measurement.

(11) REL ∆ key

By pressing REL∆ to enter the relative measurement state, the meter will remember the value

measured at the time when pressing the key(it is called the initial value), and after that the value

displayed in the meter will be equivalent to the present value – the initial value. By pressing the key

again the relative measurement state will be exited. Pressing the key will be void during the

seconds the meter will automatically turn off the backlight. It is also possible to turn off the

backlight by pressing the LIGHT key before the five seconds.

(14) ~ Hz key

During the voltage or current measurements, by pressing ～Hz key the meter will enter the linear

frequency measurement state. At this time what being measured is the frequency of voltage or

current. By pressing this key again it will exit the linear frequency measurement state.

(15) LCD screen

Used for displaying the measuring results and various symbols.
