Model 1£ºVT-10S voltage sorting instrument
Instructions for use:
1. Screen display: the upper display voltage V=0.00V, the first three digits in the lower line display the lower limit voltage 3.70V, and the middle three digits display the upper limit voltage 4.20V
, the last three digits show the mode status ON1, OFF, ON2.
2. Voltage setting method: the first group of up and down arrows is the button for setting the lower limit voltage, up and down, and the latter group of up and down arrows is for setting the upper limit voltage, up and down.
3. Mode setting: press the mode button to select ON1 mode: the measured voltage is within the set upper and lower limits, and the buzzer will beep in green, (the measured voltage will be outside the set upper and lower limits, and the buzzer will not be called and light in red).
4, OFF mode: turn off the buzzer, the measured voltage will be green within the upper and lower limits of the set voltage, and the red light will be bright outside the range.
5. ON2 mode: Contrary to ON1 mode, when the measured voltage is outside the upper and lower limits of the set voltage, the buzzer will beep and the red light will be on, and the measured voltage will be within the range, the green light will be on, and the buzzer will not beep.
Second, technical parameters
1. Input power supply; AC220V
2. Weight; 0.5KG
3. Fuse; 0.5A
4. Meter range; 9.99v
5. Resolution; ¡¾10mV
6. Alarm mode; buzzer
Three, matters needing attention;
1. When measuring, the red test lead is connected to the positive electrode of the battery, and the black test lead is connected to the negative electrode of the battery.
2, the measured voltage shall not be higher than 10V,
Note: It cannot be displayed if the range is exceeded, or the instrument will be burned out.
Fourth, troubleshooting
1. There is a display on the power supply screen, but it cannot be measured. Check whether the test pen is in good contact and whether the test pen is disconnected.
2. There is no alarm when measuring voltage, check whether the setting parameters are within the voltage range of the battery under test, and whether the mode selection switch is turned on (¡°OFF¡± does not alarm).
3. There is no power supply when the machine is turned on, check whether the socket is in good contact and whether the power cord is disconnected.
