9. Derating Curve
The derating curve of the absolute maximum input voltage in common mode is shown as
follows and valid for both models RT-ZD002 and RT-ZD003.
10. Inspection Procedure
a. Connect the BNC output connector to the vertical input of a general purpose
oscilloscope.
b. Install four AA cells or connect an appropriate power lead.
c. Set the oscilloscope input coupling to 1 M
Ω
, DC and to 1V/div. Center the trace on the
display.
d. Connect the inputs of the probe to power lines, using an appropriate power socket to
4 mm adapter.
e. Set the range of the probe to 1/100 (RT-ZD002) or 1/200 (RT-ZD003).
f. Then, a 50 Hz/ 60 Hz sine-wave of proper amplitude will be displayed on the screen of
the oscilloscope and this means the probe is working properly.
11. Cleaning
Use a soft cloth to clean the dirt. Prevent damage to probe.
a. Avoid immersing the probe.
b. Avoid using abrasive cleaners.
c. Avoid using chemicals contains benzene or similar solvents.
