4-10. Continuity performance test:
1. Insert the black test lead into the
'
COM
'
terminal and the red one into the
'
V/
Ω
/Hz
'
terminal.
2. Turn the selector knob to
range, press the SELECT key to select the continuity measurement
mode.
3. Place the test leads onto two points of the tested circuit, if the inner buzzer sounds, the resistance is
less than 50
Ω
.
Note: Never input voltage at “
” range.
4-11. Temperature measurement
1. Turn the selector knob to the
°
C/
°
F range.
2. Using the TP01 temperature probe insert the cathode (black pin) of the cold end (free end) of the
probe into the
'
mA
'
terminal jack and the anode (red pin) into the
'
V
Ω
Hz
'
terminal. Put the working
end (temperature measurement end) of the thermocouple on the surface or inside the object to be
tested. Read the temperature from the screen, and the data is in Centigrade.
3. Press the SELECT key to select Fahrenheit, the data is in degrees Fahrenheit.
Note:
1.
When the input terminal is in ambient air, it will display the ambient temperature.
2.
Only use the TP01 probe or the temperature accuracy isn’t guaranteed.
3.
Never input voltage at temperature range.
4.
Never use the TP01 probe to determine the temperatures of liquids or vapors since it can cause an
internal short circuit in the meter.
4-12. Data holding
1. The presently measured value is held on the LCD and the HOLD symbol displays. Press the HOLD
button again, the HOLD function is cancelled.
4-13. Auto power off
1. When the meter has not been used for about 15 minutes, the built-in buzzer will sound 5 times and
the meter goes into sleeping mode, 1 minute later, the buzzer sounds a long tone 1 time and the meter
powers off. Press any key to restart the power.
4-14. Meter maintenance
The VCVC88E is a high accuracy precision instrument, please do not attempt to modify any of the
internal circuits.
1. Keep the meter away from water, dust and shock.
2. Do not store and operate the meter under extremes of high temperature, high humidity,
combustibles, explosives and strong magnetic areas.
3. Wipe the case with a damp cloth and a mild detergent, do not use abrasives and alcohol.
4. If do not operate the meter for a long time, you should take out the batteries to avoid leakage,
corrosion and damage to the meter.
5. When the
symbol displays, you should replace the battery following the steps:
5-1. Unlock the button and remove the battery case;
5-2. Take out the old batteries and replace with new ones. Alkaline batteries are better and have a
longer service life.
5-3. Fit on the battery case and lock the button;
Note:
1. Never input a voltage value higher than 1000VDC or 750VAC
2. Never measure a voltage with the meter selector knob in the current, resistance, temperature,
capacitance or diode and continuity range.
3. Never use the meter without a battery installed and the back case closed securely.
4-15. Trouble shooting
If the meter does not work properly, check the meter as following:
