Matters needing attention
1. In order to ensure the accuracy of measurement and calibration, please
preheat the product for at least 5 minutes before measurement, especially for
calibration, it is best to preheat for more than 20 minutes. After preheating,
the calibration parameters can be more accurate.
2. When the battery is powered, the internal noise of the product is the
smallest, so it is recommended to measure under battery power. Especially when
doing calibration operations, it is strongly recommended to perform under battery
power. When the charger is connected, if the quality of the charger is not good,
there will be some noise.
3. Please do not connect the computer USB charging port to charge, the signal
of the USB port will seriously interfere with the working state of the product,
resulting in serious inaccurate product measurement.
4. Please use better quality fixtures.
5. Before measurement and calibration, please make sure that there is no
strong interference signal around to avoid the inaccurate measurement result
caused by interference.
6. Charge the battery in time after being under power to avoid long-term power
shortage.
7. The interface is BNC. Since copper has a relatively lower strength than
other metals, please protect it as carefully as possible to avoid falling and
bump damage.
8. In the case of strong interference, unconventional operation, and unknown
bug of software, a crash may occur (power may be consumed until the battery is
exhausted after the crash). At this time, please directly reset the product to
