Offset Test
4-25. Equipment Required. This procedure does not require any test equipment.
1. Set the HP 3457A t o the DC Current function (DCI), 300 uA range, and the number of digits dis-
played (DIGITS DISP) to six.
2. Use the Test Record t o record the current offset readings on the 300 uA, 3 mA, 30 mA, 300 mA
and 1 A ranges.
3. If any of the offset readings are beyond the limits specified in Table 4-5 and on the Test Record,
the instrument should be calibrated or repaired. Refer to Section V of this manual f o r calibration
procedures.

Gain Test
4-27. Equipment Required. A DC Current Soi~rce capable of providing currents of 300 LIA, 3 mA, 30 mA
(k .007O/o), 300 mA
(+
.026O/o), and 1 A
(+
.04%) is required for the following procedure.
1. Set the DC Current Source to 300 uA and connect it to the HP 3457A front panel
I
and
LO
input
terminals.
2. Set the HP 3457A t o the 300 uA range and the number of digits displayed (DIGITS DISP) t o six.
3.
Use the Test Record t o record the full-scale current readings for the 300 uA, 3 mA, 30 mA, 300 mA
and 1 A ranges.
4. If any of the full-scale readings are beyond the limits specified in Table 4-5 and o n the Test
Record, the instrument should be calibrated or repaired. Refer to Section V of this manual f o r
calibration procedures.
5. Reduce the output of the DC Current Source and disconnect it from the HP 345714 inpiit terminals.
