RESISTANCE
Range 1 kn to 10 Mn
Resolution 1 non 1 kn range (reading at least 10% of full scale)
Accuracy (+20°C to +30°C, batteries only)
NOTE
When operating on power-line voltage, add 10°C
to the ambient temperature for internal heating
before computing accuracy.
1 kn
Within 0.5% of reading ±3 counts. Temp Coef is (within
0.03% of reading +0.04% of full scale) per °C
10 kD to 1 Mn Within 0.5% of reading ±1 count. Temp Coef is (within
0.02% of reading+ 0.02% of full scale) per °C
10 M~ Within 1% of reading ±1 count. Temp Coef is (within 0.05%
of reading+ 0.02% of full scale) per °C
Accidental Voltage Input Protection 125 V max on all ranges
Sett Ii ng Ti me 2 seconds for reading within 2 counts
Reference Current
1
Approximately 100 µA, 100 µA, 10 µA, 1 µA, and 100 nA
for ranges 1 kn through 10 Mn respectively
NOTE
The potential across the unknown resistance is
1 V per 1000 counts on the 10 kn through
10 Mn ranges and 0. 1 V per 1000 counts on the
1 kn range. This potential is negative at the
mA-n jack with reference to common.
