Frequently Asked Questions - FG-30802T VOLTCRAFT

How do I measure DC voltage with the FG-30802T?

Set the rotary switch to the DC voltage range (V with straight and dotted lines). Connect the black test lead to COM and red to VΩHz. Touch the probes to the circuit and read the display. Ensure the range is appropriate or use auto-ranging.

What is the maximum current I can measure?

The FG-30802T can measure up to 10 A AC/DC. For currents above 400 mA, use the 10A input jack. Never exceed the rated current to avoid damage.

How do I test continuity?

Turn the dial to the continuity symbol (diode with sound waves). Connect leads as usual. If resistance is below about 50 Ω, the meter will beep. Use this to check fuses, wires, and connections.

How to replace the battery?

Remove the test leads, turn off the meter, and undo the screw on the back cover. Lift the cover, replace the 9V battery (6LR61), and reattach the cover. Dispose of old battery properly.

Can I measure temperature with this multimeter?

Yes, you can measure temperature from -20°C to 1000°C using a type K thermocouple (not included). Set the dial to °C/°F, insert the thermocouple into the COM and VΩHz jacks, and read the temperature. Be careful with hot surfaces.

What does CAT III 600V mean?

CAT III 600V indicates the meter can safely measure circuits in fixed installations (like distribution panels) up to 600V phase-to-earth. Always choose a meter rated for the measurement category of your application.

How to measure AC current using the clamp?

The FG-30802T does not have a built-in clamp. To measure AC current, you must break the circuit and use the 10A input. Alternatively, use an external clamp accessory if supported. Never measure current on live wires without proper isolation.

How do I clean and maintain the multimeter?

Clean the exterior with a dry cloth. Do not use solvents. Check test leads for damage regularly. Replace leads if insulation is cracked. Store in a dry place to prevent internal damage.

Why does the display show 'OL'?

'OL' stands for Overload, meaning the measured value exceeds the selected range. Switch to a higher range or use auto-ranging. If it persists, the input may be too high for the meter. Remove the probes immediately to avoid damage.

What spare parts are available?

Common spare parts include test leads, a type K thermocouple, and a 9V battery. For internal repairs, contact a qualified technician or the manufacturer. Use only specified fuses for current measurement protection.

Glossary

Pulse Width

PW is an abbreviation for pulse width and is divided into positive pulse width negative pulse width.

The positive pulse width is the time interval from 50% of the rising edge to 5 the adjacent falling edge.

The negative pulse width is the time interval from 50% of the falling edge to the adjacent rising edge.

The pulse width is determined by the period and duty cycle of the signal. The calculation formula is pulse width = period * duty cycle.

Duty Cycle

In a series of ideal pulse sequences (such as a square wave), the ratio of the of the positive pulse to the total pulse period.

Pulse/Duty Cycle

The pulse width is defined as the time interval from the 50% threshold of the amplitude of the rising edge of the pulse to the 50% threshold of the amplitude the next falling edge, as shown in the following figure.

- The settable range of pulse width is limited by the "minimum pulse width" "pulse period"

Pulse width ≥slant minimum pulse width

Pulse width ≤slant pulse period - minimum pulse width

- The pulse duty cycle is defined as the pulse width as a percentage of the period.

- The pulse duty cycle is associated with the pulse width, and modifying one parameters will automatically modify the other parameter. The pulse duty is limited by the "minimum pulse width" and "pulse period".

Pulse duty cycle ≥slant minimum pulse width ÷ pulse period × 100%

Pulse duty cycle ≤slant (1 - 2 × minimum pulse width ÷ pulse period) × 100%

$$ f (t) = A _ {1} \sin \left(2 \pi f _ {1} t + \varphi_ {1}\right) + A _ {2} \sin \left(2 \pi f _ {2} t + \varphi_ {2}\right) + A _ {3} \sin \left(2 \pi f _ {3} t + \varphi_ {3}\right) + \dots $$

Generally, the component of frequency f_1 is called the fundamental wave f_i is the fundamental

frequency, A_1 is the fundamental amplitude, and _1 is the fundamental phase. In addition, the frequency of each component is usually an integer multiple of the fundamental frequency, which is called harmonic. A component whose frequency is an odd multiple of the fundamental frequency is called an odd harmonic, and a component whose frequency is an even multiple of the fundamental frequency is called an even harmonic.

This signal source can output up to 16 harmonic orders. After selecting CH1 or CH2, press the front panel 📂 button to enter the harmonic setting menu. You can set the parameters of the fundamental, select the type of output harmonics, specify the maximum number of output harmonics, and the amplitude and phase of each harmonic.

Synchronize

Our instruments can output basic waveforms (except noise), arbitrary waveforms (except DC), harmonics, sweep waveforms, burst waveforms, and synchronized waveforms of modulated waveforms from a single channel or simultaneously from

two channels. This signal is output from the front panel [Sync] connector.

(1) Sync Switch

The default is "on", which sends the sync signal to the [Sync] connector. The output level on the [Sync] connector is a logic low when the sync signal is turned off.

(2) Synchronization signal of various waveforms

• For sine, square, ramp and pulse waves, the sync signal is a square wave with a 50% duty cycle. When the waveform output is positive, the sync signal is TTL high with respect to the 0V voltage (or DC offset value). When the waveform output is negative, the sync signal is TTL low relative to the 0V voltage (or DC offset value).
• For an arbitrary waveform, the sync signal is a square wave with a variable duty cycle. When the output waveform amplitude reaches a certain value, the sync signal is TTL high.
• For harmonics, the sync signal is referenced to the harmonic order and is a square wave with a variable duty cycle. When the output waveform amplitude is positive, the sync signal is TTL high.
• For AM, FM, PM, and PWM, for internal modulation, the sync signal is referenced to the modulation frequency, and the sync signal is a square wave with a 50% duty cycle. In the first half of the modulation waveform, the sync signal is TTL high. When external modulation is performed, there is no sync signal output.
• For ASK, FSK, PSK, BPSK, 3FSK, 4FSK, the synchronization signal is referenced to the keying frequency, and the synchronization signal is a square wave with a duty cycle of 50% . There is no sync signal output during external modulation.
• For OSK, the sync signal is referenced to the keyed frequency and the sync signal is a square wave with a 50% duty cycle. When the internal crystal oscillator starts, the sync signal is TTL high.
• For N-cycle bursts, the sync signal is TTL high at the beginning of the burst. At the end of the specified number of cycles, the sync signal is TTL low (if the waveform has an associated start phase, it may not be a zero crossing). For an infinite count pulse train, the sync signal is the same as the sync signal of the continuous waveform.
• For external gated bursts, the sync signal follows its gate signal. Note: This signal does not become TTL low until the end of the last cycle (if the waveform has an associated starting phase, it may not be a zero crossing).

Here's how to connect to a computer. First, install the Waveform Editor software on the CD-ROM on your computer. Then, there are several connection options to choose from.

Using USB Port

(1) Set the USB device protocol type of the signal generator: Press Utility → I/O Setup → USBDEV, switch to PC.
(2) Connection: Connect the USB Device interface on the rear panel of the signal generator to the USB interface of the computer with a USB cable.
(3) Install the driver: Run Waveform Editor software on the computer, press F1 to view the built-in help documentation. Follow the instructions to install the driver. The path of the driver is the USBDRV folder in the directory where the Waveform Editor communication software is located.
(4) Host computer communication port setting: Open the Waveform Editor software, click "Communications" in the menu bar, select "Ports-Settings", in the setting dialog box, select the communication port as "USB". After the connection is successful, the connection status prompt in the lower right corner of the software interface turns green.

Using LAN Port

Connect Directly

(1) Connection. Plug one end of the network cable into the LAN connector on the rear panel of the signal generator; the other end is plugged into the LAN interface of the computer.
(2) Set the network parameters of the computer. Since the signal generator does not support automatic IP address acquisition, you need to specify the IP yourself. Here we set the IP address to 192.168.1.71.
(3) Set the network parameters of the host computer. Run Waveform Editor software on the computer. In the "Communications" menu, under "Ports-Settings", select the communication port as "LAN", the IP is set to be the same as the first three fields of the computer's network IP in step (2), and the last field has a different IP address. It is "192.168.1.99"; the port can be set to

any value from 0 to 4000. However, since ports below 2000 are often occupied, it is recommended to set it to 2000 or higher. Here, it is set to "3000".

Figure 5-1 Setting the network parameters of the host computer

(4) Set the network parameters of the signal generator. In the signal generator, press Utility → I/O Setup → Network setting to enter the submenu. Set the IP address and port to the IP and port in the PC software port settings in step (3). After the shutdown and restart, if the data can be obtained normally in the PC software, the connection is successful.

Connect through a Router

(1) Connection. Connect the LAN interface on the rear panel of the signal generator to the router with a network cable. The computer is also connected to the router.
(2) Set the network parameters of the computer. Since the signal generator does not support automatic IP address acquisition, you need to specify the IP yourself. The default gateway and subnet mask settings must match the settings of the router. For example, the IP address is set to 192.168.1.71, the subnet mask is set to 255.255.255.0, and the default gateway is set to 192.168.1.1.
(3) Set the network parameters of the host computer. Run Waveform Editor software on the computer. In the "Communications" menu, under "Ports-Settings", select the communication port as "LAN", the IP is set to be the same as the first three fields of the computer's network IP in step (2), and the last field has a different IP address. It is "192.168.1.99"; the port can be set to any value from 0 to 4000. However, since ports below 2000 are often occupied, it is recommended to set it to 2000 or higher. Here, it is set to "3000".

Figure 5-2 Set the network parameters of the host computer

(4) Set the network parameters of the signal generator. In the signal generator, press Utility → I/O Setup → Network setting to enter the submenu. Set the IP address and port to the IP and port in the PC software port settings in step (3). The gateway settings need to be the same as the gateway settings of the router. After the shutdown and restart, if the data can be obtained normally in the PC software, the connection is successful.
