2. Use tlie Test Record t o record the 30 mV. 300 niV. 3 V, 30 V and 300 V full-scale readings begin-
ning with t h e 30 mV range.
3. Test t h e HP 3457A accuracy at one-tenth o f full-scale o n the 300 V, 30 V, 3 V a n d 300 m V ranges.
Set t h e HP 3457A t o each range and the AC Signal Source to p r o \ ide a ~ o l t a g e equal t o one-tenth o f
the full-scale
\
alue o f t h e range selected. Use t h e Test Record t o record t h e readings f o r each range.
4.
If a n y o f t h e gain readings a r e beyond the limits specified in Table 4-2 and o n t h e Test Record, t h e
instrument should be calibrated o r repaired. Refer t o Section V o f this manual f o r calibration
proced LIIXS.
5. Set the A C \'oltage Standard f o r a n output o f 30 niV.
