Plug the black test lead into the COM jack (12) and the red test lead into the INPUT jack (10). Connect the probes to the measuring points (in parallel). The measurement results will appear on the LCD display (4).

ТС21:
When measuring AC current, press the FUNC button (5) to display the frequency.
ТС24/ТС32:
When measuring AC current, the frequency is displayed on LCD simultaneously.

When the voltage is greater than 80V, the orange backlight will light up.

Voltage measurement (in mV) (TC24/TC32 only)
Turn the knob switch (13) to the position and press the FUNC button (5) to select the AC or DC voltage measurement function. Plug the black test lead into the COM jack (12) and the red test lead into the INPUT jack (10). Connect the probes to the measuring points (in parallel). The measurement results will appear on the LCD display (4). When measuring AC voltage, the frequency is displayed on LCD simultaneously.

Frequency/Duty measurement
Turn the knob switch (13) to the ****position and press the FUNC button (5) to select the frequency or duty measurement function. Plug the black test lead into the COM jack (12) and the red test lead into the INPUT jack (10). Connect the probes to the measuring points or in parallel to the circuit to be measured. The measurement results will appear on the LCD display (4).

When measuring high current, continuous measurement should be no longer than 15 seconds.
To avoid damaging the device, check the fuse before measuring and use the correct jack.

Resistance measurement

Turn the knob switch (13) to the position and select the appropriate range (TC21); or
Turn the knob switch (13) to the position and press the FUNC button (5) to select the resistance measurement function (TC24/TC32).

Plug the black test lead into the COM jack (12) and the red test lead into the INPUT jack (10). Connect the probes to the resistance measuring points of circuit or resistor (in parallel). The measurement results will appear on the LCD display (4).

When measuring resistance on the line, switch off the power supply and discharge all high-voltage capacitors.

Continuity test

Turn the knob switch (13) to the position (TC21); or
Turn the knob switch (13) to the position and press the FUNC button (5) to select the continuity measurement function (TC24/TC32).

Plug the black test lead into the COM jack (12) and the red test lead into the INPUT jack (10). Connect the probes to the circuit or component to be tested (in parallel). The measurement results will appear on the LCD display (4). If the resistance is <30Ω, an acoustic signal will be emitted continuously and the green indicator lights up at the same time. If the resistance is between 30Ω to 60Ω, the red indicator lights up.

When measuring continuity on the line, switch off the power supply and discharge all high-voltage capacitors.

Diode test

Turn the knob switch (13) to the position (TC21); or
Turn the knob switch (13) to the position and press the FUNC button (5) to select the diode measurement function (TC24/TC32).

Plug the black test lead into the COM jack (12) and the red test lead into the INPUT jack (10).

Non-contact voltage detection (NCV)
Turn the knob switch (13) to the position and press the FUNC button (5) to select the NCV function. NCV (Non-contact voltage detection) is displayed. Slowly bring the NCV probe (1) close to the point to be detected. When the signal of a weak electromagnetic field is detected, the built-in buzzer will produce a slow beep sound, and the LED indicator (3) will glow green. When the signal of a strong electromagnetic field is detected, the built-in buzzer will produce a quick beep sound, and the LED indicator (3) will glow red.

When using this function, remove the test leads from the jacks.

Live detection
Turn the knob switch (13) to the position and press the FUNC button (5) to select the LIVE function. Live (Live detection) appears on the screen. Plug only the red test lead into the INPUT jack (10). Connect the red test probe to the conductor to be measured. When the signal of a weak electromagnetic field is detected, the built-in buzzer will produce a slow beep sound, and the LED indicator (3) will glow green. When the signal of a strong electromagnetic field is detected, the built-in buzzer will produce a quick beep sound, and the LED indicator (3) will glow red.

Temperature measurement
Turn the knob switch (13) to the position. Plug the black test lead of K-type thermocouple into the COM jack (12) and the red test lead into the INPUT jack (10). Connect the thermocouple probe to the object to be measured. The measurement results are shown in Celsius and Fahrenheit simultaneously.

When using the included K-type thermocouple, temperature measurement range is –40… +260°C / –40… +500°F.

Battery test (TC21 only)
The device allows you to check the actual battery voltage under a load of a certain resistance. Such assessment gives a more accurate battery condition status compared to a voltage measurement without a load. Turn the knob switch (13) to the battery test position and select the appropriate range (1.5V or 9V). Plug the black test lead into the COM jack (12) and the red test lead into the mA jack (11). Touch the positive pole with the red test lead and the negative pole with the black test lead. The measurement results (battery voltage) will appear on the display (4).

When measuring a battery in the 1.5V range, a 30Ω load resistance is used.
When measuring a battery in the 9V range, a 300Ω load resistance is used.
