3.2 DC VOLTS
There are five ranges for measuring DC voltage, 200m V, 2000m V, 20 V, 200 V, and 600 V.
For more accurate measurements use the lowest range possible without exceeding the value.
1. Connect the black test lead to the "COM" terminal and the red test lead to the "V/
Ω
" input terminal.
2. Set the function/range switch to the appropriate DC V range shown above.
3. Touch the test leads to the circuit under test. With DC voltage, the polarity of the test leads is a factor.
Touch the black (common) test lead to the negative DC source first and red (positive) test lead to the “live” source second.
4. Read the value of the measurement displayed. If the leads are reversed a "-" indicator will appear on the display.
5. Typical DC Voltage measurements include car batteries, automotive switches and household batteries.
3.3 RESISTANCE
There are five ranges for measuring resistance 200, 2000, 20K, 200K, and 2000K and 2 Meg Ohms.
For more accurate measurements use the lowest range possible without exceeding the value.
WARNING
When measuring resistance always make sure the power is off.
1. Connect the black test lead to the "COM" terminal and the red test lead to the "V/
Ω
" input terminal.
2. Set the function/range switch to the appropriate resistance (ohms) range shown above.
3. Touch the test leads to the resistor or non-energized component to be measured. Use the 2000K range when testing for resistance values in electronic
components such as resistors and potentiometer. If the value of the component falls within the range of another setting, reset the function/range switch
to that setting for a more accurate reading.
4. Read the value of the measurement displayed. With resistance measurements, the polarity of the test leads is not a factor.
5. Typical resistance/continuity measurements include resistors, potentiometer, switches, extension cords and fuses.
3.4 HOUSEHOLD BATTERY TESTING
There are three ranges for measuring common household batteries, 1.5V, 9V, and 12V.
1. Connect the black test lead to the "COM" terminal and the red test lead to the "V/
Ω
" input terminal.
2. Set the function/range switch to the appropriate battery position.
3. Touch the test leads to the positive and negative terminals on the battery. With DC voltage, the polarity of the test leads is a factor.
Touch the black (common) test lead to the negative (-) terminal and the red test lead to the positive (+) terminal.
4. Read the value of the measurement displayed. If the leads are reversed a "-" indicator will appear on the display.
4. BATTERY REPLACEMENT
Note: When the battery’s voltage drops below the operating voltage, the mark “
” will appear
on the LCD to indicate the the batteries must be replaced.
Caution: When changing the battery, disconnect the test leads from the circuit completely.
Turn the meter off before removing the batteries.
1. Remove protective boot from test unit.
2. Remove the screws in the back cover of the tester and carefully separate the back cover from the front.
3. Remove the battery from the contacts, noting the polarity of the battery terminals and contacts.
4. Replace with one fresh 9 volt battery.
Note: Do not use rechargeable batteries in this unit.
5. Carefully, replace the back cover and tighten the screws.
Do not overtighten the screws as this may strip the threads in the tester housing.
6. Replace protective boot.
5. AUTO OFF
1. To turn the meter back on if it turns off because of the auto off function, first turn the dial to the off position.
Then turn the dial from the off position to any function to turn the meter back on.
