clip being the signal input line and the black being the input ground. The matching cable at the
output PZT OUTPUT terminal is a three-wire output. Two red clips are two independent single-
electrode output lines, and the black clip is a common ground.
When connecting a load such as a piezoceramic (PZT) through a three-wire output cable,
carefully determine the polarity of the marking on the matching cable, otherwise the load such as
piezoelectric ceramic (PZT) may be damaged.
When one end of a probe of an oscilloscope or similar instrument is connected to the ground, do
not directly measure the PZT OUTPUT terminal or the two electrode terminals of the mating cable,
otherwise a short circuit will occur.
If a two-phase socket is used to connect the power supply end of the oscilloscope, when the probe
of the oscilloscope is separated from the ground, the PZT OUTPUT end or the two electrode ends
of the matching cable can be directly measured, but the voltage of the two electrode ends should
be less than 300V, otherwise oscilloscope will be damaged.
You can directly measure the PZT OUTPUT terminal or one electrode of the matching cableand
ground (Uo1 or Uo2 to the ground) through an instrument such as an oscilloscope. When
the output voltage exceeds 300V, pay attention to the measurement voltage range of the test
instrument such as an oscilloscope, otherwise the measuring instrument will be damaged.
The multimeter with 1000V range can directly measures the voltage at either end. When the
output voltage is greater than 1000V, please use a multimeter with a suitable voltage range to
measure the voltage at either end.
When measuring a high voltage with a low-voltage tester, it can be measured by a resistor divider
method. It is recommended to connect six 1MΩ/2W resistors in series that connect with one end of
the electrode and the ground or both ends of the electrode, and measure the voltage across one 1
MΩ/2W resistor.
When measuring the two electrode ends of the PZT OUTPUT terminal, be careful that the
instrument probe cannot be connected to the ground.
Before the power is turned off, adjust the DC-OFFSET knob to zero and the input voltage of the
CONTROL INPUT terminal is 0V, so that the output voltage of the PZT OUTPUT terminal is 0V, so
as to prevent the PZT OUTPUT terminal from having a voltage output when the power is turned
on next time, to prevent the human body from getting an electric shock.
