16.13 AP202
Current probe
The AP202 current probe uses an advanced magnetic sensor to accurately measure current signals by testing
magnetic field signals generated by current. It is mainly used for measurement and analysis of conductor current.
The probe
’
s current measurement range is 20A (DC + ACpk), which can measure the frequency bandwidth of
current signals up to 25MHz. The option can be purchased by users. The option number is 4456-H08.
16.13.1 Instructions for Safe Use
To ensure the safety of users and the product and the equipment connected to the product, you shall strictly
observe the following safety operation specifications:
Use correct power adapter: You must use the original power adapter of this product to avoid damage to
the probe.
Master and use correct connection and disconnection methods: Ensure that the tested object is dead
before connecting or disconnecting the object.
Master and use correct connection and disconnection methods: When connecting, connect the probe
output end to the test instrument and then connect the probe input; when disconnecting, disconnect the
test input and then disconnect the probe output end.
Grounding: This product is connected to the earth of the oscilloscope through the BNC output terminal.
It is necessary to ensure reliable grounding during use.
Pay attention to the voltage range of measured objects of this product to avoid exceeding the range.
Do not use this product with the product case open. Non-professionals do not open the casing of this
product.
Do not use the instrument in flammable or explosive environments.
Do not use the instrument in too humid environments. Keep this product dry and tidy.
16.13.2 Operating Instructions
When the AP202 current probe is used, the input impedance of the oscilloscope is set to 1M
Ω
, the probe type is
set to current, and the probe attenuation is set to the same as that of the AP202.
The AP202 current probe is easy to use, but users who are not familiar with this product should read this manual
completely before starting the operation:
1
）
Make sure the input power supply voltage of the power adapter is normal before use.
2
）
In order to obtain accurate measurement results in different test cases, demagnetization and DC balance
adjustment should be performed before the test. The specific steps are as follows:
Warm up the oscilloscope for 20 minutes and set the vertical offset of the oscilloscope channel for
connecting the probe to zero
Connect the output BNC of the current probe to the input end of zeroing channel of the oscilloscope
Keep the test card slot of the current probe empty and toggle the sliding switch on the card slot upper
cover to ensure that the upper cover is well closed
Press the demagnetizing button and adjust the balance knob to make the display signal zero
