2, The Soviets had difficulty in producing high resistance millivoltmeters; the
z i,lhivoltiaeters they made had resistances no higher than 75 to 100 ohms. For 50X1-HUM
yrimariizy German
rectifier-tyre AC instruments - all were of the iron vane type. There
was no apparent lack of oscilloscopes, yet very few vacuum tube voltmeters wet
in evidence. A few recording instruments were available, but most indicating
instruments were millivoltmetere, These were calibrated periodically? using .a
potentiometer and a standard cello The standard cells were of Soviet manufacture,
of the uneaturated type, and proved very satisfactory. Various special
instrument assemblies were b. " olving simple electronic circuits of no
particular originality-. Van instrumentation problems dealt with 50X1-HUM
therriocouples. and thhrm#,o ?ouple r ss allations . There was difficulty in obtaining
thermocouple wire of sufficiently high uniformity.
