Using NULL
Using NULL on 2k OHM range only.
c * Using NULL on 200 OHM range only.
When the NULL function is not used, add ±200 milliohms to all readings.
ACCURACY for the 200 Ω. 2 KΩ,
20 KΩ, 200 KΩ, 2 MΩ, and 20 MΩ
ranges:
Normal Conversion Rate
(1.6 readings per second)
+ 18°C to +28°C
200 Ω range
±(0.015% of r 0.015% of full
scale) 0
2 kΩ to 200 kΩ ranges
±(0.015% of r 0.01% of full
scale) 0
2 MΩ range
±(0.10% of r 0.01% of full
scale)
20 MΩ range
±(0.15% of r 0.005% of full
scale)
0°C to + 18qC,
+ 28qC to +50qC
For the typical accuracy for a given
temperature in this range, add to the
+ 18q C to +28qC accuracy the following
tolerance, per degree deviation from
+ 18°C or +28°C.
200 Ω range
±(0.06% of reading + 0.06% of full

2 kΩ to 200 kΩ ranges
±(0.06% of reading + 0.035% of full
scale)0
±(0.002% of reading + 0.001% of full
