1.5 Specification
1.5.1 Measurement Accuracy
5000/5001
5002
The accuracy is quoted at full rated current with auto average current mode and the display
count is 30,000* plus sign and unit
The 200m
Ω range has a scale length of 20,000
1.5.2 Programmable current
The measurement current is adjustable on each resistance range as follows:
The accuracy of current is typically ±0.25%
