4. OPERATING INSTRUCTION 4.1 DATA HOLD If you need data hold when measuring, you can put on “HOLD”, it will hold the reading; if you put the button again, data hold will not continue. 4.2 FUNCTION TRANSFORM Put down the "FUNC" when measuring the current and voltage. Meter will be transformed between DC and AC range. Put "FUNC" when measuring the resistance, capacitance, diode and continuity, meter will transform among them. 4.
Press the "Hz%" again, meter will recover the Hz range. When measuring at the voltage range and current range, put down the " Hz%" to be Hz range and the frequency of the signal for the voltage and current are measured then. Press the " Hz%" again to be the DUTY range and the DUTY CYCLE of the signal for the voltage and current are measured then. Press the " Hz%" again, meter will be back to the condition of the voltage and current measuring.
NOTE: LED is the main source of back light. Its working current is large, although the meter has the timer equipment (time is 5 seconds and it will off automatically after 5 seconds); often use back light will shorten the battery life, you’d better not to use the back light so frequently if it’s not necessary. When the battery voltage is less than 7V, it will show “ ”.
recover the working condition. If presses the “FUNC” when power is on, auto power off disable. 4.8 PREPARATION FOR MEASUREMENT 4.8.1 Turn the transform switch.
