Basics: Using Digital Clock

Guide Digital clock
1) Introduction of digital clock DIGITAL
Digital Clock Digital has some advantages over mechanical clock, which is highly accurate, the resistivity of the higher clock so as not to cause pressure drops measured in weak electrical currents, the measured frequency alternating way, but this clock has some disadvantages electronically is running up or down, hard look at the results in case of rapid measurement, does not measure the magnification of capacitor charging.

Guide:

2) - Measure the DC voltage (or AC)

Set the clock to scale voltage DC or AC

• To watch the red rod socket "VΩ mA" jack rod into the black "COM"
• Press the DC / AC to DC if selected scale is measuring voltage DC or AC if the measured voltage AC.
• Turn the switch on position "V" go to scale the highest voltage if not known, if the decimal value report, we reduce the scale below.
• Place the scale on the voltage to be measured and read the value on the LCD screen of the watch.
• If the measuring stick upside down (with DC) clock will report a negative value (-)

3) - Measure the DC current (AC)

• Move the elevator stick down clock mA if measured small stream, or 20A if the large current measurement.
• Turn the switch on position "A"
• Press the DC / AC current measurement to select DC or AC
• Place the measuring rod connected to the circuit to be measured
• Read the value displayed on the screen.

4) - Testers

• Return the position when the plug voltage measurements.
• Turn the switch on the measuring position "Ω", if unknown resistor value is chosen high scale, if the result is decimal, then it decreased.
• Place the probe into the two resistors.
• Read the value on the screen.
• Resistance measurement function can measure the communication circuit, assuming the wire measured by a scale or, if the circuit is called advanced clock generated

5) - frequency measurement

• Turn the switch on position "FREQ" or "Hz"
• To scale such as when measuring voltage.
• Place the probe on the measured points
• Read the value on the screen.

6) - Measurement of Logic

• Logic is measured in the measuring circuit of (Digital) or measuring the foot of microprocessors, which essentially measure Logic state power - The "1" or no electricity, "0", measuring as follows:
• Turn the switch on position "LOGIC"
• Place the red rods in place to measure the mass black rod
• Display only "▲" is logic high level report, only "▼" is reported with a low logic

7) - Measurement of other functions

• Digital multimeter clock also a number of measurement functions such as measurement diodes, capacitors Measure, Measuring Transistor But if we measure the components above, we use mechanical clock up will result in better and faster measurement
