7. How to use Function Switches
7-1 SELECT Key
This key is to chose the measuring function at Ω/ Diode Check/ Continuity/ function and Current function(uA, mA, A). Actions at each function are as below.
● Ω/ Diode Check/ Continuity function
When setting the instrument to "Ω/ Diode Check/ Continuity" function, "Ω"measuring mode has been selected in the initial condition. By pressing "SELECT"
Key, measuring mode changes.
"Ω" →
"Continuity Check" →
"Diode Check"
● Current function (uA, mA, A)
When setting the instrument to any function of the "uA", "mA", and "A", DC Current Measuring mode has been selected in the initial condition.
By pressing "SELECT" Key, measuring mode changes.
"DC" →
"AC"
7-2 MIN/MAX Key
Press the "MIN/MAX" Key to lock MAX or MIN value, and the "MAX
or MIN" sign will appear on the display, press it over 2 seconds to exit.
It cannot display bar graph on MAX/MIN HOLD mode.
7-3 RANGE Key
At each "ACV", "DCV", "Ω", "uA", "mA" and "A" function, setting for the measuring ranges can be done manually by pressing "RANGE" Key. ("Auto" symbol
disappears from the display.)
Every time when pressing "RANGE" Key, range moves.
In order to change from manual mode to Auto-ranging, there are following 2ways.
1) Press "RANGE" Key for 2seconds
2) Change to the other functions.
7-4 REL Key
The difference between measured values can be indicated on the display at each "ACV", "DCV", "Ω", "Capacitance", "ACA" and "DCA" function.
When pressing "REL" Key, "△"symbol lights up and the value under measuring is stored.
After that, the difference between stored value and measuring value is indicated on the display.
It can be released by pressing the "REL" Key again, changing to the other functions.
Note) Do not press "REL" Key over 2 seconds to cause the malfunction.
It can be released again by pressing "REL"Key over 2 seconds.
7-5 HOLD Key
The measured value can be hold at all functions.
By pressing "HOLD" Key, "DH" symbol indicated on the display and the indicated value can be held.
By pressing "HOLD" Key again, "DH" symbol disappears from the display and held data is released.
7-6 Hz/DUTY Key
Making measurement for frequency of input signal and DUTY(Pulse width / Pulse period).
(1) Change from normal measurement to "Frequency Measurement" and "DUTY Measurement".
Every time when pressing "Hz/DUTY" Key, it changes in the following sequence from normal measurement.
"Frequency" → "DUTY" → "Normal measurement"
(2) Change Frequency and DUTY at "Hz/DUTY" function.
By pressing "Hz/DUTY" Key, it changes in the sequence : "Frequency" → "DUTY".
