• Select the corresponding function scale.
• Insert the red test lead into the “positive” jack, and the black into the “COM” jack.
• Connect test leads with both ends of the measured objects.
Caution:
• Do not input voltage above 600V to prevent electric shock or damage. The input impedance of each range scale is 10MΩ,
this load eect in high resistance measurement may cause error. If the input impedance is lower than 10kΩ, the error can
be ignored (≤0.1%).
• Be cautious lo avoid electric shock when measuring high voltage.
• Please check the functions by applying a known voltage before use.
9.3 Continuity Test/Resistance/Diode/Capacitance
Measurement (Picture 4)
Select the corresponding function scale.
Insert the red test lead into the “ ” jack, and the black into the “COM” jack.
Connect teat leads with both ends of the measured object.
Caution:
• Do not input voltage above DC 60V or AC 30V to avoid personal injury.
• Please disconnect all the other parts of the circuit to avoid inaccuracy
• Before the resistance online measurement, please do disconnect all the power and fully discharge all capacitors to avoid
injury or device damage.
• If the resistance is over 0.5Ω when the test leads are shorl-circuited, please check the test leads for looseness or other
abnormalities
• If the measured resistor is open or the resistance exceeds the maximum range, the LCD will display “OL”.
• Measured value = displayed value - probe short circuit value
• It is recommended lo use “REL” measurement mode for capacitance less than 100nF.
9.4 Temperature Measurement (MP780808 only, Picture 5)
• Select the temperature measurement function scale.
• Insert K-type thermocouple lo the meter x the temperature probe on the measured object, and read after the value is stable.
