Volth S-11 Operating Instructions Manual - page 8
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.
(3) connect the test pen to the measured circuit, get the frequency value. press
Hz/DUTY”key
,it displays“Hz”,change it to “%” to get the ratio.
Caution :
(1) Frequency grade can not set measuring range manually, no simulation strip display.
(2) If the measured frequency is above 30V, please press “Hz/DUTY” key at “ACV”
measuring range to frequency function for measure. By this method, it can bear
700V voltage,in case the voltage is too high to damage the meter . it can reduce
the voltage to the best range IC is able to deal.
4.9 temperature measure Turn the
range switch to C°/F°
, insert the k type black plug to “COM”jack, insert red one to
“V/Ω/Hz ”jack
, the meter displays the temperature now .
Caution :
When the meter without inserted with temperature tool, it displayd environment
temperature
(normal temperature).Attached K type WRNM-010,the temperature
is 250C° (482 F°)
.
V. Maintenance
5.1 when the meter displays “ ”
,must replace the battery. Open the battery
cover, replace with the same type new battery to keep it work well.
5.2 keep the meter and test pen clean, dry and not damaged, could use the clean cloth
or cleanser to clean the cover
,do not use abrasive or solvent.
5.3 avoid damage, shake, shock
,avoid high temperature and strong magnetic field.
5.4 should be corrected at least once per year
VI. Accessories
6.1 Test lead: 1 set
6.2 users manual: 1 piece
6.3 Temperature sensors: 1 set
6.4 cloth bag: 1piece
Warnings!
before open the cover or the battery cover, cut off the power
source and test pen and any input signal, in case electric shock.
