b. Connect the probe tip and the probe common clip
together and note the reading. Then disconnect them
and note the reading.
c. CHECK-Readings are within .0020 of each other.
3. CHECK CHARACTER GENERATOR
a. Set VOL TS-mA/DIV to 1 (blue scale).
b. Connect the probe to the DC Voltage Standard with
a dual banana-plug to BNC adapter and probe adapter.
Set the Standard to +1.005 volts.
c. CHECK-Readout displays +1.005.
d. Rotate the Standards 100 mV selector from O through
9 ( 1.005 to 1.905).
e. CHECK-Millivolt digit on the readout displays a 0
through 9 (+1.005 through +1.9005).
4. CHECK POLARITY INDICATION
a. Note the polarity of the reading on the display.
b. Reverse the banana plug connector at the Standard.
c. CHECK-Display reverses polarity sign.
d. Reset banana-plug connector for positive inputs.
5. CHECK DC VOLTAGE MEASUREMENT ACCURACY
a. Set VOL TS-mA/DIV and the DC Voltage Standard as
shown in Table 5-4.
b. CHECK-Reading is within limits shown in Table 5-4.
6. CHECK RMS CONVERTER DC VOLTAGE RESPONSE
a. Set RMS pushbutton in.
b. Set VOL TS-mA/DIV to 1 (blue scale).
c. Set the DC Voltage Standard to +1.000 V.
d. CHECK-Reading of 1.000 ± 0.025 (0.975 to 1.025).
