(8) Probe Short-Circuit Detection Function
(9) Contact Improvement Function
(10) Current Mode Setting Function
(11) Scaling Function
(12) Zero Adjustment Function
Operation An error is detected after a certain period following the output of EOM signal output if a
connection between H
POT
and H
CUR
or L
POT
and L
CUR
terminals lasting more than
1 ms is found.
Default setting OFF, 5 ms
Setting Function ON/ OFF
Probe short-circuit detection time: 1 ms to 100 ms
Threshold 500 Ω fixed (reference value)
Operation Allows a contact improvement current (by applying oxidized film breakdown voltage) to
flow between H
POT
and H
CUR
, and L
POT
and L
CUR
terminals (for each range).
The PULSE setting applies the contact improvement current for only 100 µs or 300 µs
before measuring.
When VOLT LIMIT is ON or LOW POWER is ON, applies the contact improvement cur-
rent for only 300 µs before measuring.
Default setting ON, Current-limited to 35 mA (100 m
Ω
range to 100 k
Ω
range, LOW POWER: ON for
all ranges)
PULSE, Current-limited to 35 mA (300 k
Ω
range to 100 M
Ω
range)
Setting OFF/ ON/ PULSE
Applied voltage 20 V max
Current limit 17 mA, 25 mA, 35 mA, 50 mA (peak current reference value)
Operation Sets whether or not to apply the measurement current while measurement is not being
carried out. (for each range)
The CONT (continuous) setting is available only when the Contact Improver function is
disabled.
Default setting PULSE
Setting CONT/ PULSE
Operation Corrects measured values using a linear expression “y = ax + b “ (setting affects all
ranges)
Default setting OFF, a = 1, b = 0
Setting ON/OFF
Coefficient a 0.50000 to 2.00000
Offset b ±0.0000 m Ω to ±99.9999 M Ω
Operation Nullifies wiring resistance when measuring with the two-terminal method.
Default setting OFF, 0 Ω
Adjustment range -1
Ω
to 10
