Ermenrich Zing TC20 Digital Multimeter
EN
Please carefully read the safety instructions and the user manual before using this product. Keep away from children. Use the device
only as specified in the user manual.
The kit includes: digital multimeter, test probes (red and black), user manual, and warranty.
Install batteries
Open the battery compartment cover and insert the batteries according to the correct polarity marks. Close the cover.
Getting started
Press and hold the power button (7) for 3 seconds to turn the device on/off
Press the power button (7) to select an option.
Press the HOLD button (6) to save data. Press and hold the HOLD button (6) for 2 seconds to turn the power auto-off function on/off.
Do not connect the device to voltages exceeding DC 1000V or AC 750V as it may cause damage to the device.
!
Observe the safety precautions to avoid the risk of electric shock.
Voltage measurement
1. Insert the black wire into the COM input (9) and insert the red wire into the VΩ input (10).
2. Touch the testing points using the black test probe and the red test probe (11) correspondingly. Ensure the firm contact of the test
probes with the testing points.
3. If the voltage is greater than 0.6V (AC or DC), the multimeter will compare the AC and DC components of the voltage and will select a
greater value, and then it will automatically select the required measurement range (6V / 60V / 600V / 1000V). The measurement result
will be displayed on the screen.
4. Disconnect the test probes from the tested circuit after the measurement completion.

Resistance measurement
1. De-energize the closed loop under test and discharge the capacitors. Otherwise, if the voltage in the loop is greater than 0.6V, the
multimeter will mistakenly enter the voltage measurement mode.
2. Insert the black wire into the COM input (9); insert the red wire into the VΩ input (10).
3. Touch the testing points using the black test probe and the red test probe (11). Ensure the firm contact of the test probes with the
testing points.
4. Then the multimeter will automatically select the required measurement range (600Ω / 6kΩ / 60kΩ / 600kΩ / 6MΩ / 60MΩ). Then the
measurement result will be displayed on the screen.
Disconnect the test probes from the tested circuit after the measurement completion.
!
To perform an accurate measurement of low resistance, subtract the internal resistance of the test probes from the obtained
measurement result value (touch the red test probe with the black test probe to measure the internal resistance of these test probes).
!
If the measured resistance at both ends of the test probes is less than 50Ω, the multimeter will emit a continuous sound. Press the
power button (7).
