Ermenrich Zing TC33 Digital Multimeter

Please carefully read the safety instructions and the user manual before using this product. Use the device only as specified in the user manual. Keep away from children.
The kit includes: digital multimeter, test leads (red and black), K-type thermocouple, carry bag, user manual, and warranty.
Charging mode
Whenever the charger is connected, the multimeter enters the charging mode.
The charge symbol is displayed on screen and an analog bar with the battery charge level in percent appears. It takes about 3 hours to befully charged. The warning symbol is displayed.
Do not take measurements while charging.

Getting started

Press and hold the Power button (1) for 2 seconds to turn the device on/off. This multimeter has two modes – Smart (Auto) and Professional (Manual). When turned on, it displays Auto (Automatic mode) and enters the Smart (Auto) measurement mode. In this mode, DC voltage, AC voltage, resistance, continuity can be measured, and the multimeter can automatically identify the measurement signal. Press the FUNC button (3) to activate the manual mode. Then, press the SEL button (2) to select the required function.
To return to Smart (Auto) mode, press and hold the FUNC button (3) for 2 seconds.
Data hold
During a measurement, press the H/Flashlight button (4) to turn on data hold function and display the current reading. Press again to turn the function off and return to measurement display.
Flashlight
Press and hold the H/Flashlight button (4) for 2 seconds to turn the flashlight on/off.
MAX/MIN mode
Press the MAX/MIN button (5) to switch between the maximum and minimum values. Press and hold (5) for 2 seconds to exit this function.
Fuse Broken indication
When the fuse is blown, FUSE BROKEN is displayed during measurement.
When the fuse is blown, the display shows FUSE when a lead is inserted in the A jack (7) and no further measurements will be taken.
Input jack indicator
When the function set is changed, the corresponding input jack light will flash 5 times to indicate that the test lead should be inserted into the corresponding jack.
Automatic recognition of the current measurement
When the probe is inserted into the A jack, the multimeter automatically switches to the automatic recognition of current measurement function set ( ); switching function sets will not be allowed at this time.
When the multimeter is switched manually to the current function set and no lead is inserted in the A jack, the display shows LEAd (Lead needs to be inserted) and no further measurement is taken.
Auto power turn-off
When you press the Power button (1) to power on, the automatic turn-off function is activated by default and the display shows the symbol. After 15 minutes without any key operation, the multimeter will turn off automatically to save battery energy.
To cancel the automatic turn-off function, press and hold the MAX/MIN button (5) and the Power button (1) simultaneously.
The symbol is not displayed when the automatic turn-off function is canceled.
Do not measure voltage higher than 600V; otherwise, the device may be damaged.
Observe the safety precautions to avoid the risk of electric shock.

Smart (Auto) measurement mode
The multimeter is turned on in Smart (Auto) measurement mode by default. In this mode, DC voltage, AC voltage, resistance, and continuity can be measured, and the multimeter can automatically identify the measurement signal.
Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the measuring points or in parallel to the circuit to be measured. The multimeter will automatically recognize the measured signal. If the resistance is <50Ω, an acoustic signal will be emitted continuously. The measurement results will appear on the VA display (6).
Professional (Manual) measurement mode
AC/DC voltage measurement
Press the FUNC button (3) to select the function. Press the SEL button (2) to select AC voltage or DC voltage. The symbol or   symbol is displayed accordingly. Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the measuring points. The measurement results will appear on the VA display (6).
Resistance measurement
Press the FUNC button (3) to select the function. Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the resistance measuring points of circuit or resistor. The measurement results will appear on the VA display (6).
Continuity test
Press the FUNC button (3) to select the function. Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the circuit or component to be tested. The measurement results will appear on the VA display (6). If the resistance is <50Ω, an acoustic signal will be emitted continuously.
AC/DC voltage measurement (in mV)
Press the FUNC button (3) to select the function. Press the SEL button (2) to select AC voltage or DC voltage. The symbol or symbol is displayed accordingly. Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the measuring points. The measurement results will appear on the VA display (6).
Frequency and duty cycle measurement
Press the FUNC button (3) to select the function. Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the measuring points or in parallel to the circuit to be measured. The measurement results will appear on the VA display (6).
Capacitance measurement
Press the FUNC button (3) to select the   function. Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the probes to the capacitance to be measured. The measurement results will appear on the VA display (6).
Diode test
Press the FUNC button (3) to select the function. Plug the black test lead into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the black test probe to the cathode side and the red test probe to the anode side of the diode to be measured. If the polarity of the test probes is reverse to the diode polarity, the OL (Overload) will appear on the screen. This can be used for distinguishing the anode and cathode side of a diode. The measurement results will appear on the VA display (6).
Temperature measurement
Press the FUNC button (3) to select the function. Plug the black test lead of K-type thermocouple into the COM jack (8) and the red test lead into the INPUT jack (9). Connect the thermocouple probe to the object to be measured. The measurement results will appear on the VA display (6).
AC/DC current measurement
Press the FUNC button (3) to select the function. Or insert the red probe into the A jack (7) to automatically select the function. The symbol is displayed and the multimeter enters the DC current measurement mode. Press the SEL button (2) to display the  symbol and enter AC current measurement mode. Plug the red test lead into the A jack (7) and the black test lead into the COM jack (8). Disconnect the measured power supply, connect the multimeter in series with the power supply, and then turn on the measured power supply. The measurement results will appear on the VA display (6).
Non-contact voltage detection (NCV)
Press the FUNC button (3) to select the NCV/Live function. NCV is displayed. Slowly bring the NCV probe close to the point to be detected.
When the signal of a weak electromagnetic field is detected, the “– – – L” will appear on the screen, the built-in buzzer will produce a slow beep sound, and the LED indicator will glow green. When the signal of a strong electromagnetic field is detected, the “– – – H” will appear on the screen, the built-in buzzer will produce a quick beep sound, and the LED indicator will glow red.
** When using this function, remove the test leads from the jacks.
Live detection
Press the FUNC button (3) to select the NCV/Live function. Press the SEL button (2) to display the LIVE symbol. Plug only the red test lead into the INPUT jack (9). Connect the red test probe to the conductor to be measured. When the signal of a weak electromagnetic field is detected, the “– – – L” will appear on the screen, the built-in buzzer will produce a slow beep sound, and the LED indicator will glow green. When the signal of a strong electromagnetic field is detected, the “– – – H” will appear on the screen, the built-in buzzer will produce a quick beep sound, and the LED indicator will glow red.
Fuse replacement**

• Turn off the multimeter power and remove the probes.
• Remove the screws fixing the back cover and remove the back cover.
