2WR
Connection
a. 2WR is a connection method for 2 wires.
b. When 2WR is performed, EX SNS in Fluke5720A should be turned
OFF
c. 2WR connection method is shown as the diagram below.
Appendix 4
Common
problems
1. If there is no display on the screen after turning the power on
Please
plug out the Calibration Key, and turn the power on again.
2. If the resistance value is unstable at the
100MΩreange
When
calibrating the high resistance, users need to use a high-voltage
insulated cable (over 1KV rating) as the test connection cable.
3. If the device is still not accurate after all resistance ranges have been
adjusted
Because the 0R and OPEN affect all resistance ranges
parameter, users need to adjust CAL CODE1 through to 9 all at once.
You cannot calibrate each CAL CODE 1 separately.
4. AC10mV & AC1mA is not accurate
Because AC10mV and AC1mA
is calculated from the ATE program, users can
’t adjust this manually. If
AC10mV or AC1mA is not accurate, it is necessary to use the ATE
program to calibrate them again.
