Oscilloscope Function Introduction

1. Probe Inspection
   > Security:
   To avoid electric shock when using the probe, ensure that your finger is located behind the safety ring on the probe body. When the probe is connected to a high voltage power supply. do not touch the metal parts on top of the probe. The measurement voltage must not exceed the probe specification (1X range up to 150V, 10X range up to 300V), otherwise the instrument may be damaged.

   Manual Probe Compensation:
   When connecting a probe to an oscilloscope for the first time, it is recommended to perform the following compensation checks, as uncompensated or offset probes can cause measurement errors. If probe compensation is required, perform the following steps:
   1. Power on, connect the probe to the signal input terminal, and input 4V/1KHz square wave signal.
   2. Press the AUTO key on the panel! to view the waveform. > Manual Probe Compensation:
   When connecting a probe to an oscilloscope for the first time, it is recommended to perform the following compensation checks, as uncompensated or offset probes can cause measurement errors. If probe compensation is required, perform the following steps:
   1. Power on, connect the probe to the signal input terminal, and input 4V/1KHz square wave signal.
   2. Press the AUTO key on the panel to view the waveform. 3. If you need to adjust, you can adjust the capacitance on the probe to change the compensation state; The adjustment tool is an accessory adjustment rod or a suitable non- metal handle adjustment rod that comes with the probe.
   The adjustment method is shown in the following figure > Probe Attenuation Setting:
   The probe attenuation factor setting will affect the vertical scale reading of the signal. Make sure that the multiple of the attenuation switch on the probe matches the multiple of the probe attenuation option in the oscilloscope system setting, when the multiple of the switch is set to X1, the multiple of the oscilloscope is set to X1, when the muttiple of the switch is set to X10, the multiple of the oscilloscope is set to X10.

2. Channel Setting 1. Press F1 to switch between CH1 and CH2 and select the channel to be configured.
   2. Press F2 to enable or disable the channel switchover. The waveform of the current channel is displayed when the channel switchover is on.
