4.1 Open Circuit Compensation and Short Circuit Compensation
42
Compensation Error:
If a compensation error occurs, a warning beep will sound and the state
becomes as follows.
The measurement frequency at which the error occurred can be ascertained
from the underbar display.
See
"MAIN display area ERROR display" (p. 14)
What if there is an error?
• Are the measurement terminals open? Open the measurement terminals
and then perform compensation again. (To set the measurement terminals
open, short the H
CUR
terminal to the H
POT
terminal, and the L
CUR
terminal
to the L
POT
terminal.)
• If there is a compensation error even when the measurement terminals are
open, external noise may be affecting compensation or the unit, probe, or
fixture may be malfunctioning. Use the shielding process, submit the unit
or fixture for repairs, or replace the probe with a new one. (The probe can-
not be repaired.)
See
Appendix 2 "Measurement of High Impedance Components" (p. A3)
If is pressed, the unit enters short circuit compensation incorporate
mode. (Proceed to Step5) (The settings for open circuit compensation remain
the same as last time.)
5.
Use a shorting bar to create a short circuit state between the
HIGH terminal and LOW terminal of the probe or fixture con-
nected to the measurement terminals.
Use a shorting bar with as low an impedance as possible.

Compensation stops.
When performing compensation, make sure that there is no noise source
nearby. Noise may cause an error when performing compensation.
ex. Servo Motor, switching power source, high-voltage cable and etc.
(Example)
• When performing compensation, the placement of things like the probe and
fixture and the distances between terminals must be as similar as possible
to the state when performing measurement.
• If you do not want to perform short circuit compensation, press to
return to normal measurement mode.
• When using 4-TERMINAL PROBE 9140, please pinch the short wire with
both clips. A short circuit state can not be created by pinching clip each other.
