5. Setup
5.1. Battery Installation
If the battery symbol appears on the display, it indicates that the battery should be replaced. To replace the 9V battery (NEDA 1604 or 6F22 type), remove the 2 screws in the bottom of the case. Simply remove the old battery and replace it with a new one. Be careful to observe battery polarity.
5.2. Connecting Test Leads
Always ensure the test leads are securely connected to the appropriate jacks on the multimeter before taking any measurements. The red test lead is for positive (+) connections, and the black test lead is for common (COM) or negative (-) connections.
6. Operating Instructions
Before taking any measurement, ensure the multimeter is set to the correct function and range. If the value to be measured is unknown, start with the highest range and gradually decrease it until a satisfactory reading is obtained.
6.1. AC Voltage Measurement
- Connect the red test lead to the "V.Ω" jack and the black test lead to the "COM" jack.
- Set the rotary switch to the desired ACV position.
- Connect test leads across the source or load being measured.
- Read the voltage value on the LCD display.
6.2. DC Current Measurement
- Connect the red test lead to the "mA" jack and the black test lead to the "COM" jack. (For measurements between 200mA and 10A, move the red lead to the "10A" jack.)
- Set the rotary switch to the desired DCA position.
- Open the circuit in which the current is to be measured and connect test leads in series with the circuit.
- Read the current value on the LCD display along with the polarity of the red lead connection.
6.3. Resistance Measurement
- Connect the red test lead to the "V.Ω" jack and the black test lead to the "COM" jack. (The polarity of the red lead is positive "+").
- Set the rotary switch to the desired "Ω" range position.
- Connect test leads across the resistor to be measured and read the LCD display.
- If the resistance being measured is connected to a circuit, turn off power and discharge all capacitors before applying test probes.
6.4. Diode Test
- Connect the red test lead to the "V.Ω" jack and the black test lead to the "COM" jack. (The polarity of the red lead is positive "+").
- Set the rotary switch to the diode symbol position.
- Connect the red test lead to the anode of the diode to be tested and the black test lead to the cathode of the diode. The approximate forward voltage drop of the diode will be displayed. If the connection is reversed, only figure "1" will be shown.
6.5. Transistor (hFE) Test
- Set the rotary switch to the "hFE" position.
- Determine whether the transistor under testing is NPN or PNP and locate the emitter, base, and collector leads. Insert the leads into the proper holes of the hFE socket on the front panel.
- Read the approximate hFE value at the test condition of base current 10 μA and Vce 3V.
NOTE:
- To avoid electrical shock, remove test leads from measurement circuits before testing a transistor.
6.6. Continuity Test
- Connect the red test lead to "V.Ω" and the black test lead to "COM".
- Set the rotary switch to the buzzer symbol position.
- Connect test leads to two points of the circuit to be tested. If continuity exists, the built-in buzzer will sound.
6.7. Temperature Measurement
- Connect the temperature line (K-type thermocouple) to the appropriate input terminals.
- Set the rotary switch to the temperature position.
- Place the thermocouple probe in direct contact with the object or environment whose temperature is to be measured.
- Read the temperature value on the LCD display.
6.8. DC Voltage Measurement (Batteries)
- Connect the red test lead to the "V.Ω" jack and the black test lead to the "COM" jack.
- Set the rotary switch to the desired DCV position.
- Connect test leads across the battery terminals.
- Read the voltage value on the LCD display.
6.9. DC Voltage Measurement (Regulated Power Supply)
- Connect the red test lead to the "V.Ω" jack and the black test lead to the "COM" jack.
- Set the rotary switch to the desired DCV position.
- Connect test leads across the output terminals of the DC regulated power supply.
- Read the voltage value on the LCD display.
6.10. Backlight Function
Press the "BACK LIGHT" button to turn on the screen light. This feature is useful for working in low-light conditions.
6.11. Important Precaution for Current Measurement
WARNING: Multimeter measure the current must be measured in series to the circuit.
When measuring electric current, it is crucial to pay attention to the most important rule: do not mix the measure method and measure the voltage current. Use the multimeter's current function, choose an appropriate range (if the current value is unknown, choose a bigger size range to prevent the multimeter from displaying "1"), then insert the red test lead into the mA hole and the black test lead into the COM hole. Disconnect the circuit part and connect the red and black test leads in series to the measuring circuit.
7. Maintenance
7.1. Cleaning
Do not use abrasives or solvents on the meter. To clean it, use a damp cloth and mild detergent only.
7.2. Battery & Fuse Replacement
If the battery symbol appears on the display, it indicates that the battery should be replaced. Fuses rarely need replacement and blow almost always as a result of operator's error.
To replace the battery or fuse (F500mA/250V), remove the 2 screws in the bottom of the case. Simply remove the old component and replace it with a new one. Be careful to observe battery polarity.
WARNING:
Before attempting to open the case, always be sure that test leads have been disconnected from measurement circuits. Close the case and tighten screws completely before using the meter to avoid electrical shock hazard.
8. Troubleshooting
If the multimeter is not operating properly, first check the battery and fuse. Ensure they are correctly installed and not depleted or blown. Verify that the test leads are properly connected and not damaged. If issues persist, consult the detailed instructions in the manual or contact customer support.
9. User Tips
- Always double-check the function and range settings before making a measurement to prevent damage to the multimeter or the circuit being tested.
- When measuring current, remember to connect the multimeter in series with the load and ensure the correct current jack (mA or 10A) is used.
- For resistance measurements, always ensure the circuit is de-energized and any capacitors are discharged.
- The backlight feature is very useful in dimly lit environments; don't forget to use it when needed.
