∗
1 Negative values can be up to -10% full scale.
The maximum display range is 9,999,999 dgt. or 9 G
Ω
.
(If the maximum measurement range is exceeded, the over-range display will be shown even if the value is less
than or equal to the maximum display range.)
∗
2 • When LP: OFF, 0.001% f.s. = 10 dgt. However, when using the 100 M
Ω
range or greater with the 100 M
Ω
range
high-precision setting off, 0.01% f.s. = 1 dgt. With LP: ON, 0.001% f.s. = 1 dgt.
•
Measurement accuracy is the accuracy after zero-adjustment. When not performing zero-adjustment, the value
indicated under [Additional accuracy without 0ADJ] is added.
•
Values in parentheses on the second row apply when OVC is on. Only OVC on values are provided in the “Low
Power: ON” table.
•
During temperature correction, the following value is added to the resistance measurement accuracy rdg. error:
t
0
: Standard temperature [°C]
t
: Current ambient temperature [°C]
Δ
t
: Temperature measurement accuracy
α
t0
: Temperature coefficient [1/°C] at
t

∗
3 Measurement current accuracy is ± 5%
When using the 1,000
Ω
range or lower with an external trigger source or with continuous measurement off (non-
free-run), the measurement current is only applied from the start of measurement (TRIG = ON) to the end of mea-
surement (INDEX = ON). The measurement current is stopped at all other times. When using the internal trigger
source with continuous measurement on (free-run), the measurement current is stopped while the contact check
indicates an error.
∗
4 When using an external trigger source or when continuous measurement is off (non-free-run), the open voltage is
limited to 20 mV or less from 1 ms after the completion of measurement (INDEX = ON) until the start of the next
measurement (TRIG = ON).
