Series 3700 System Switch/Multimeter Reference Manual  Section 14: Verification 
3700S-901-01 Rev. C / July 2008  14-3 
Line power 
The Series 3700 requires a line voltage of 100V to 240V (±10%), and a line 
frequency of 50Hz or 60Hz. 
NOTE  The instrument automatically senses the line frequency at power-up. 
Recommended test equipment 
The following table summarizes recommended verification equipment. You can 
use alternate equipment if that equipment has specifications equal to or greater 
than those listed in the table. Note, however, that test equipment uncertainty will 
add to the uncertainty of each measurement. Generally, test equipment 
uncertainty should be at least four times better (more accurate) than 
corresponding Series 3700 specifications. 
NOTE  The Keithley Instruments Model 3706-190 backplane connector board 
is an accessory that can be used to make connections to the 
calibrator. Additional boards, such as a 4-wire short or the discrete 
resistors, would also be convenient to eliminate rewiring for different 
setups used in verification.
