4. Operating Instructions
4.1 Power On/Off
Press and hold the power button (ⓘ) to turn the device on or off.
4.2 Basic Measurement
The ZT-DQ01 features automatic identification of resistors, capacitors, and inductors. Simply connect the component to the test leads, and the meter will automatically detect the component type and display the relevant parameters (L, C, R, Z, X, D, Q, θ, ESR).
4.3 Function Buttons
- FREQ: Adjusts the test frequency (100Hz, 120Hz, 1KHz, 10KHz, 100KHz).
- LEVEL: Sets the test level (0.1V, 0.3V, 0.6V).
- SPEED: Adjusts the measurement speed (Slow, Medium, Fast).
- X/D/Q/θ/ESR: Cycles through displayed sub-parameters.
- AUTO/S/P SETUP: Automatic series/parallel mode setup.
- LCRZ: Selects the main measurement parameter (Inductance, Capacitance, Resistance, Impedance).
- HOLD/REC: Holds the current measurement or enters record mode.
- REL TOL%: Relative measurement and tolerance percentage.
4.4 Discharging Capacitors
WARNING: Always discharge capacitors before testing to prevent damage to the meter or injury.
