Volth S-11 Operating Instructions Manual - page 7
4.4 Resistances
1) Adjust the revolving the Range switch to Ω position, and this time the measuring
appliance will be set for the resistance measuring range.
2) Insert red table pen into the V/Ω/Hz jacks, black table pen into " COM " jack.
3) Connect the pen with the beginnings and ends of the test circuit to read the
resistance value.
4) If the manual choice measuring range scope is needed, press RANGE to choose.
When the table pen is overloaded input, display monitor can display " OL ".
4.5 Measurement of forward voltage of diode
(1) turn the Range switch to “ ”position. press “SELECT” to measuring range
(2) insert the red pen to “V/Ω/Hz” jack, insert the black pen to COM” jack. (red pen “+”)
(3) connect the test pen to the two ends of the measured to read positive voltage.
(4) when the diode is reverse connected or the input end leads the way, the display
monitor can display " OL ".
(5) the diode does not have the simulation strip display.
4.6 Connection & disconnection measure
(1) turn the Range switch to “ ” position, press“SELECT”key to measuring
range.
(2) insert red pen to “V/Ω/Hz” jack, insert black pen to“COM” jack.
(3) if the measured resistance is less than about 50Ω,the buzzer will beep. This is
the pass or break measure.
Caution
:
a. when the input end leads the way, it displays “OL”
.
b. the measured circuit should be measured under the off-power condition,
because any overload signal would make the buzzer beep, thus cause wrong
measure.
4.7 capacitance measur
(1 ) turn the Range switch to “ ”position . General type press “SELECT” key
to CAP measuring range.
(2) insert the red pen to “V/Ω/Hz” jack, insert black pen to “COM” jack.
(3) connect the test pen to the two ends of the measured capacitor, could get the
capacity value.
(4) capacity position can not set the measuring range manually, no simulation strip
display. when the capacity value is big, the measure may need about 10 seconds.
4.8 frequency/DUTY measure
(1) turn the Range switch to Hz measuring range.
(2) insert red pen to “V/Ω/Hz/CAP”jack, insert black pen to “COM” jack.
Warnings!
Before the survey of resistance, one must guarantee that the
measured electric circuit or part does not have the voltage.
Warnings!
When measure the electric capacity, must guarantee the
measured capacitor has sent the electricity out, if the big electric
capacity contains the oversized non- electric capacity ingredient,
possibly affects the measuring accuracy.
