5.2.3
Touch
key to start the program of 25 Ohm CALIBRATION.
The instrument will display the following message:
* 25 Ohm CALIBRATION
Connect a 25 Ohm
Standard Resistor
and Press Enter
Menu= Exit Enter = Yes
-------------------------------------------
5.2.4
Follow the “Connect a 25 Ohm Standard Resistor and Press
Enter” instructions to connect a 25Ω standard resistor to Probe 1
(S1). A standard resistor of 25Ω must have a resistance close to
25Ω, otherwise the calibration will not be accurate.
5.2.5
Touch
key to start the 25Ω calibration. The instrument will
display “Waiting…” for a few seconds while the resistance is
calculated, and the following message will appear:
25.9977
Rt =25.0000 OHM
Menu= Exit Enter = Yes
25R Rs = OHM
* 25 Ohm CALIBRATION
5.2.6
The value on the third line is the parameter to be adjusted and
this value must match the standard resistance of the 25Ω resistor.
For example, the above figure shows the current value as
25.9977, but the standard resistor’s value is 24.9977. This value
can be adjusted by using
or
key to move the “_”
