13. The readout should be within the limits of
0.000 kn to 0.001 kn.
14. Set the MODE/RANGE control to RESISTANCE/
200 kn.
15. The readout should be within the limits of
00.00 kn to 00.01 kn.
16. Set the MODE/RANGE control to RESISTANCE/
2Mn.
17. The readout should be within the limits of
.0000 Mn to .0001 Mn.
18. Set the MODE/RANGE control to RESISTANCE/
20Mn.
19. The readout should be within the limits of
0.000 Mn to 0.001 Mn.
20. Remove the banana-plug patch cord connecting the
I NPUT connectors together.
21. The readout display (M 1/7D12 only) will display a
> symbol and will indicate a high value of resistance. The
unit is attempting to measure the resistance between the
INPUT connectors. Since this value exceeds the 20 Mn
range, the display indicates the symbol> for over-ranging.
This concludes the operational check procedure.
Resistance
22. Connect a pair of test leads to the INPUT
connectors.
23. Connect a 10 kn resistor between the test leads.
(The value of the resistor is not critical for this
demonstration.)
24. The readout display will read the value of the
resistor used. Set the MODE/RANGE switch to
RESISTANCE/2 Mn, RESISTANCE/200 kn and
RESISTANCE/20 kn and notice that the reading changes
to include more significant figures.

25. Set the MODE/RANGE control to
RESISTANCE/2 kn and observe that the> symbol appears
to indicate over-ranging.
DC Voltage
26. Remove the resistor from the test leads, and connect
the COM test lead to the oscilloscope ground post.
27. Set the oscilloscope Calibrator 4 V and the Rate
(Calibrator) switch to DC.
28. Set the MODE/RANGE switch to DC VOL TS/20 V.
29. Touch the HIGH test lead to the oscilloscope
Calibrator output.
30. The readout will read about +4.000 V (the exact
reading will depend upon the accuracy of the oscilloscope
calibrator) .
31. Reverse the test lead connections; i.e., connect the
HIGH test lead to the ground post and the COM test lead to
the calibrator output.
32. The readout should read the same value of voltage as
in step 30 but with a - polarity indicated.
Temperature
33. Connect a voltage/temperature probe such as the
P6058 to the M 1 Probe connector (see M 1 Options at the
end of this section). Observe the precautions relating to
proper alignment of the connectors as given in the Probe
instruction manual.
34. Set the
MODE/RANGE
control
to
TEMPERATURE.
35. The readout should read the room temperature
within the limits listed in Table 2-1 of the M 1 Specification
section. (Alternate Procedure: Place the probe in an
environment having, known temperature.)
36. Connect the I NPUT connectors to the TEMP OUT
pin jack connectors with the test leads. The COM connector
should be connected to the right hand TEMP OUT
connector (ground).
