1. Connect the test leads across the capacitor to be tested.
2. Wait until the reading on the primary display is stable, then read the

capacitance reading on the primary display. The secondary display shows the ambient temperature.

Note:

1. Before measurement, make sure that the capacitor to be tested has been discharged thoroughly.
2. For measurements >10uF , it may take about 30 secs for the meter to complete measurement and stabilize reading.

Measuring Frequency and Duty Cycle

1. Connect the black test lead to the "COM" terminal, and the red test leads to the "INPUT" terminal.
2. Set the rotary switch to the Hz position.
3. Connect the test leads to the source or circuit to be tested.
4. The primary display shows the frequency reading, and the secondary display shows the duty cycle of the square wave signal being measured.

Note:

1. For frequency measurements, range change is automatic, and measurement range is: 0 10MHz .
2. The voltage of input signal is required to be in the range of 2V rms 20V rms. The higher the frequency of input signal, the higher the required input voltage.

Measuring Temperature

Note

To avoid possible damage to the meter or other equipment, remember while the meter is rated for -20oC to +1000oC and -4oF to 1832oF, the Type Thermocouple provided with the meter is rated to 250oC. For temperature out of that range, use a higher rated thermocouple.

The K Type Thermocouple provided with the meter is a present, it is professional and can only be used for non-critical remarks. For accurate measurements, use a professional thermocouple.

1. Set the rotary switch to the TEMP position. The secondary display shows the environment temper
2. Connect the negative " - " plug of the K Type thermocouple to the " COM " terminal, and the positive "+" plug of the K Type thermocouple to the " INPUT " terminal.
3. Connect the sensing end of the thermocouple to the object to be tested.
4. Wait a while until thermal equilibrium between the thermocouple probe and the object is reached, then read readings on the screen. The primary display shows the celsius measured temperature of the object under test, and the secondary display shows the Fahrenheit measured temperature of the object under test.

Non-Contact AC Voltage Detection

1. Set the rotary switch to the NCV position. The symbol "NCV" appears on the upper area of the screen. The primary display shows "", the secondary display shows the environment temperature. (See Figure 3.)

2. Move the NCV sensor at the" mark on the meter clamp close to the object to be tested. When the meter detects electric field generated I ac voltage, the red LED on the meter will flash and the meter will indicate the intensity of the electric field being detected. The intensity of the elecl field being detected is indicated by the number of the bar-graph segment shown at the vertical center of the display ( see Figure 4 ), the flashing of the red LED, and the beeping rate of the built-in buzzer. The higher intensity of the electric field is detected, the larger the number of the bar-graph segments shown on display, the faster the flashing rate of the red LED and beeping rate of the buzzer.

Figure 3

Figure 4

Note:

1. Detection Range: 90V - 1000V

Required Voltage Frequency: 50Hz/60Hz

1. The optimal detecting position of the meter is at the " " mark on the meter clamp.

2. If an ac voltage is not within the meter's detecting capacity/distance, the meter can not detect this voltage.

3. The meter's electric field intensity indication is affected by the magnitude of the ac voltage of the conductor under test, the distance between the meter and the conductor, the insulation of the conductor etc.

4. Because of the meter's detection limit, a line ( or conductor) under test may be electrically live even if the buzzer does not sound, the red light does not flash and the display does not indicate the presence of electric field.

5. Before and after each use, verify the meter's operation by detecting a known AC voltage. Do not use the meter if it operates abnormally or malfunctions.
6. To avoid electric shock, do not touch any conductor with your hand or skin.
7. To avoid interference, don't perform non-contact ac voltage detection in an environment with strong electromagnetic field; otherwise the detection result may be wrong.

Automatic Power-Off

The meter will turn off automatically and go into Sleep mode if you have operated the meter for about 15 minutes. To arouse the meter from Slee just press a button.

To disable the automatic power-off feature, turn the rotary switch from "OFF" position to other switch settings while holding down the Function

Selector Button; the symbol will be absent from the display.

MAINTENANCE

Warning

Except for replacing batteries, never attempt to repair or service the mete

Store the meter in a dry place when not in use. Don't store it in an environment with intense electromagnetic field.

General Maintenance

Periodically wipe the case with a damp cloth and a little mild detergent. not use abrasives or solvents.

Dirt or moisture in the terminals can affect readings. Clean the terminals follows:

1. Set the rotary switch to OFF position and remove all the test leads from the meter.
2. Shake out any dirt which may exist in the terminals.
3. Soak a new swab with alcohol.
4. Work the swab around in each terminal.

If the meter fails, check and replace (as needed) the batteries and/or review this manual to verify proper use of the meter.

Replacing the Batteries

Warning

To avoid false readings, which could lead to possible electric shock or personal injury, replace the batteries as soon as the low battery indicates.

Turn off the meter, remove the test leads from the meter and the met clamp from any conductor under test before opening the case or the battery cover.

When the low battery indicator appears on display, the batteries are not high enough and must be replaced immediately.

To replace the batteries, remove the screw on the battery cover and remove the battery cover. Replace the exhausted batteries with new ones of the same type, make sure that the polarity connections are correct. Reinstall the battery cover and the screw.
