FEATURES:

REUI 10 RECORDERS Varian's new G-40 series ten-inch poten­ tiometer recorders are—if you'll pardon the expression —five ways better: • They're compact. Die-cast a l u m i n u m c o n s t r u c t i o n and solid-state design keep weight down to 30 lbs., yet make them rugged and easy to service. • True differential input circuit means you get both high input impedance and high common mode rejection. You can even op­ erate them with unbalanced circuits. • Choose from single or multiple range models. Eight push-button ranges —1 mv to 100 volts —or single range. Attenuator ad­ justment on all. • Fast pen speed. Less than i/ 2 second full scale.

• And they are accurate. 0 . 2 5 % + 5 μν on 1 mv range; 0 . 2 5 % on all other ranges.
