Volth S-36 Instruction Manual - page 5
3.2.8 Temperature
Temperature sensor: K WRNM- 010 bare contact thermojunction
Overload protection
:effective value 250V
3.2.9 Forward voltage drop of diode
Displaying approximate forward voltage values of diode. Measuring condition:
forward direct current is 1.5mA; opposite DC voltage is about 3 V.
3.2.10 Continuity Test
•)))
In the case that the resistance between two tested points is less than about
90Ω±20Ω, the buzzer will bring up sound. Test condition:Open-circuit voltage
is about 0.5V.
IV. Operation
4.1 Instruction for control panel
(1) jaws
(2) Trigger
(3) Rotary switch : This switch is used to select functions such as current.voltage,
capacitance.resistance,temperature,frequency,forward voltage drop of diode,
continuity and turn on/off the meter.
(4) “SELECT” button: When press the key continuously, change the range of all
function for a proper range you need.
(5) “RANGE” button: One may change the measuring range by pressing this
button, press this key to cycle from small to large range of each function
(6) INRUSH:measuring Inrush voltage, current key,in AC measuring function press
the key,it will measure the Inrush value, and show the "INR" symbol in the
LCD, INRUSH function can measure current or voltage with the minimum period
up to valid values80mS,in the inrush mode, instrument automatically enter the
manual range function, if the measurement range is unknowed , press RANGE
key to the maximum range, first press the INRUSH button again inrush
measurement will be resumed, and the "INR" symbol disappear.
(7) “DH” button: The user may hold the present reading and keep it on the display
by pressing the “DH” button. Press the button again to concel the data-hold
function
(8) LCD display
(9) “VΩ”jack: This is positive input terminal for voltage,resistance
frequency,temperature,capacity and diode.
(10) “COM” jack :This is negative(ground)input terminal
(11) Barrier
