Specifications are for Channel 1 or Channel 2, after 2-hour warm-up, resolution  
at 7.5 digits (100 NPLC), with FILTERS off. RESISTANCE specifications are for  
4-wire Ohms or 2-wire ohms using Null. Without Null, add 0.2 Ohms additional  
error in 2-wire Ohms function. For Analog Filter ON, add 0.002% of reading.  
20% overrange on all ranges except 5% on Voltage Limited Resistance.  
After using Math Null. If Null is not used add 100 nanoVolts.
