Operation

BEFORE YOU TAKE A MEASUREMENT

CAUTION: If the current under measurement is higher than the selected value for a long period, overheating may take place, compromising the safety and operation of the inner circuits.

CAUTION: When connecting the lines, first connect the common (COM) test line, then connect the charged test line. When removing the lines, remove the charged test line first.

Completing a Current Measurement

WARNING: If the current range is not ,&. prevlously known, set the range to the highest range and adjust down as necessary.

WARNING: When measuring bare wires, use extra caution to avoid electrlc shock.

• Move the rotary switch (C) to the A position (1) and choose the appropriate measuring range.
• Hold the trigger (J) to open the clamp head (A), and clip one lead of the measurement circuit to be tested in the clamp (A). Connect the lead at the center of the clamp to ensure an accurate reading. Ensure you only clamp one conductor as multiple conductors with different directions will cancel out readings.
• Read the displayed value on the LCD display (F).
  

Completing a Voltage Measurement

WARNING: Do not attempt to take any voltage measurement that exceeds 600VLU AC or DC in order to avoid electrical shock and/or damage to the meter.
CAUTION: Use caution when measuring high voltages to avoid electrical shock or damage.

• Insert the black test probe (M) into the COM jack (H) and the red test probe (L) into the INPUT jack (G).
• Move the rotary switch (C) to DC voltage position (1) or AC voltage position (2).
• Connect the test probes (Land M) with the voltage source or both ends of the load in parallel for measurement and read the voltage on the display (F).
  

Completing Frequency and Duty Cycle Measurements

• Insert the black test probe (M) into the COM jack (H) and the red test probe (L) into the INPUT jack (G).
• Move the rotary switch (C) to the Vposition (1 ).
• While in voltage mode, press the Hz/% button (E) to switch to frequency measuring mode. Connect the test leads (Land M) across the circuit to be measured.
• Press the Hz/% button (E) again to switch to duty cycle mode. Connect the test leads (Land M) across the circuit to be measured.
• Read the reading on the display (F).
  Press the Hz/% button (E) to return to voltage mode.
  

Completing a Resistance Test

WARNING: To avoid injury or damage to the meter, make sure to turn off all power and discharge all capacitors before measuring resistance.

NOTE: Sometimes the resistor value and rt.4\ measured resistance differ. This is due to LJ the meter’s output test current that goes through all possible paths between leads.
NOTE: When the input end Is open, the LCD LJ shows “OL” outrange state.
NOTE: For low resistance measurements, short the test leads and record the rt.4\ resistance displayed. Then connect to the circuit and subtract the recorded resistance from the measurement for the most accurate results.

• Insert the black test probe (M) into the COM jack (H) and the red test probe (L) into the INPUT jack (G).
• Move the rotary switch (C) to the resistance position (1 ).
• Connect the test probes (Land M) to both ends of the resistor or circuit to be tested for measurement and read the reading on the display (F).

Completing a Diode Test

WARNING: To avoid injury or damage to the meter, make sure to turn off all power and discharge all capacitors before measuring diode.

• Insert the black test probe (M) into the COM jack (H) and the red test probe (L) into the INPUT jack (G).
• Move the rotary switch (C) to the diode position (1).
• Press the FUNC button (I) to switch to diode measuring mode.
• Connect the red test probe (L) and black test probe (M) across the circuit to be measured.
• Read the measured forward biased voltage drop on the display (F). If the leads are reversed, only “1” is displayed.

Completing a Circuit Continuity Test

WARNING: To avoid injury or damage to the meter, make sure to turn off all power and discharge all capacitors before measuring continuity.

• Insert the black test probe (M) into the COM jack (H) and the red test probe (L) into the INPUT jack (G).
• Move the rotary switch (C) to the continuity position (1 ).
• Press the FUNC button (I) twice to switch to continuity mode.
• Connect the red test probe (L) and black test probe (M) across the circuit to be measured. If the resistance of the circuit to be measured is less than 500, the meter’s built-in buzzer may sound.
• Read the resistance value on the display (F).
  

Completing a Capacitance Measurement

WARNING: Electric shock hazard. To avoid electric shock, before measuring capacitance, discharge the capacitance completely.

• Insert the black test probe (M) into the COM jack (H) and the red test probe (L) into the INPUT jack (G).
• Move the rotary switch (C) to the capacitance position (1 ).
• Connect the red test probe (L) and black test probe (M) across the circuit to be measured.
• Read the capacitance value on the display (F).
  

Completing a Temperature Measurement

• Move the rotary switch (C) to the TEMP position (1 ). The display will show the current ambient temperature.
• Connect the positive of the type-k thermocouple (N) to INPUT jack (G) and the negative to COM jack (H).
• Touch the tip of the thermocouple (N) to the object to be tested.
• Read the measured temperature value on the display (F).
  

Maintenance

WARNING: Before you open the meter, always disconnect it from all sources of electric current and make sure you are not charged with static electricity, which may destroy the internal components.

WARNING: Any adjustment, maintenance, or repair work carried out on the meter while it is live should be carried out by a qualified electrician.

WARNING: When you open the meter, remember that some internal capacitors can retain a dangerous voltage level even after the instrument is switched off.

CAUTION: If the meter is not going to be used for a long time, take out the battery and do not store the meter in a high temperature or high humidity environment.

BATTERY REPLACEMENT

IMPORTANT: Change the battery when the battery symbol appears on the LCD in order to avoid incorrect data.
WARNING: Do not mix old and new batteries. Do not mix alkaline, standard (carbon-zinc), or rechargeable (ni-cad, ni-mih, etc) batteries.

• Turn the meter off by turning the rotary switch (C) to the OFF position.

• Disconnect the black and red test leads (Land M) and/or any connectors from the terminals on the meter.

• Use a screwdriver to unscrew and remove the battery cover located on the back of the meter.
  

• Remove the used batteries and replace with three new AAA 1.5V batteries.

• Reattach the battery cover and secure with the screws.

TEST LEAD REPLACEMENT

Replace test leads if they become damaged or worn.

WARNING: Use test leads that meet EN 61010-031 standard and rated CAT Ill 600V or better.

Care and Cleaning

• Do not use abrasives or solvents to clean the meter. Use a damp cloth and mild detergent only. Dirty or wet input jacks can affect readings.
• Use a cotton swab with a cleaner/lubricant (such as WD-40) to clean the jacks. Use a new swab for each jack to prevent cross-contamination.
