Output impedance
(Hc terminal, when 1 kHz)
Normal mode: 100 ±10
Low impedance accuracy mode: 25 ±5
Measurement signal level (1) Open circuit terminal voltage (V) mode and constant voltage (CV) mode
• Level range
Normal mode: 5 mV to 5 V, maximum 50 mA
Low Z high accuracy mode: 5 mV to 2.5 V, maximum 100 mA
• Setting resolution 1 mV steps
• Setting accuracy
±10% of setting ±10 mV
(2) Constant current (CC) mode
• Level range
Normal mode: 10
A to 50 mA, maximum 5 V
Low Z high accuracy mode: 10 A to 100 mA, maximum 2.5 V
• Setting resolution 10 A steps
• Level accuracy
±10% of setting ±10 A
Measurement range The measurement range is determined according to impedance Z.
The values of the other measurement items can be calculated.
Ranges: 100 m
, 1 , 10 , 100 , 1 k, 10 k, 100 k, 1 M, 10 M, 100 M (10 ranges)
• The guaranteed accuracy range differs depending on the measurement conditions
(p.346).
• Out of guaranteed accuracy is displayed when out of the ranging range
OVERFLOW or UNDERFLOW is displayed when out of the A/D input range
Low Z High Accuracy Mode
• Improves measurement accuracy in the 100 m and 1 ranges.
The measurement current is increased (maximum 100 mA, maximum applied voltage 2.5
V) and the measurement accuracy is improved by setting the output resistance to 25
.
• Low Z high accuracy mode is only available for the 100 m
and 1 ranges.
