Safety Instructions

WARNING
To ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.
The meter is designed according to EN61010-1, 61010-2-032/033 and electromagnetic radiation protection EN61326-1 safety standards, and conforms to double insulation, CAT II 600V, CAT III 300V and pollution grade II. In case the meter is not used properly as instructions, the protection provided may be weakened or lost.

• Before each use verify tester operation by measuring a known voltage.
• Before use, please check if there is any item which is damaged or behaving abnormally. If any abnormal item (such as bare test lead, damaged meter casing, broken LCD, etc.) is found, or if the meter is considered to be malfunctioning, please do not use the meter.
• Do not use the meter if the rear cover or the battery cover is not covered up, or it will pose a shock hazard!
• Keep fingers behind the finger guards and away from the metal probe contacts when making measurements.
• The function switch should be placed in the correct position before measurement. It is forbidden to change the position during measurement to avoid damage to the meter!

Operating Instructions

9.1 AC/DC Current Measurement (Picture 2)

• Select the corresponding current range.
• Press the trigger to open the clamp jaws, and fully enclose one conductor.
• Only one conductor can be measured at a time, or the measurement reading will be wrong.

Caution:

• Do not insert the testing leads during current measurement to avoid electric shock.
• The current measurement must be taken with safeguard protection.
• Press the REL button to return to zero before the DC current measurement, and meanwhile the center hole of jaw should be perpendicular to the current direction to ensure accuracy.
• The open circuit zeroing reading may be relatively large after (high) DC current measurement. Please perform the AC current detection again to counteract the remanence signal by alternating electric field.

9.2 AC/DC Voltage and Voltage Frequency (% duty cycle) Measurement (Picture 3)

• 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 effect in high resistance measurement may cause error. If the input impedance is lower than 10kΩ, the error can be ignored (≤0.1%).

• Be cautious to 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 test 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 short-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 to use “REL” measurement mode for capacitance less than 100nF.

9.4 Temperature Measurement (MP60608 only, Picture 5)

• Select the temperature measurement function scale.
• Insert K-type thermocouple to the meter, fix the temperature probe on the measured object, and read after the value is stable.

9.5 NCV AC Electric Field Sensing (Picture 6a)
The electric field sensing sensitivity is divided into two levels (“EFHI” and “EFLo”). The meter defaults to “EFHI”. Users can select different sensitivity levels according to the intensity of the measured electric field. Select “EFHI” of NCV when electric field is around 220V AC 50Hz/60Hz. Bring the NCV sensing end close to a charged electric field (socket, insulated wire, etc.). The LCD will display the segment “-” with beeps and red LED flashing. As the intensity of the measured electric field increases, the more segments (—-) display , the higher frequency of buzzer beeps and LED flashes. Select “EFLo” when the electric field is around 110V AC 50Hz/60Hz.
Caution:
Use the NCV sensing end to approach measured electric field, otherwise the measurement sensitivity will be affected. When the measured electric field voltage is over 100V AC, observe whether the conductor is insulated to avoid personal injury.

9.6 Others

• Auto power off: The meter will automatically power off to save power if there is no operation for 15 min. You can wake it up by pressing any button or restart it after turning the switch to OFF.
• Press and hold the SELECT button in off state and then turn on the meter again to disable the auto power off function. Restart the meter after shut it down to resume this function.
• Buzzer: When any button is pressed or the function switch is turned, if it is valid, the buzzer will make one beep (about 0.25s). The buzzer will also beep intermittently to indicate the over range during the voltage or current measurement.
• Low battery detection: The battery voltage will be automatically detected as long as the meter is on. If it is lower than 2.6V, the LCD will display the “ ****” symbol.
• Low battery shutdown function: When the battery voltage is lower than 2.5V, the LCD displays the “ ****” symbol, the “Lo.bt” interface appears and lasts for about 10s, the buzzer makes consecutive beeps 3 times, and then the meter automatically shuts down (no is displayed).interface

Probe usage

TESTING IN CAT III MEASUREMENT LOCATIONS
Ensure the test lead shield pressed firmly in place. Failure to use the CAT III shield increases arc-flash risk.

TESTING IN CAT II MEASUREMENT LOCATIONS
CAT III shields may be removed for CAT II locations. This will allow testing on recessed conductors such as standard wall outlets.
Take care not to lose the shields.
