8. If required, the frequency marking facility of the 2010 may be used
with the Level Recorder. The control cable AQ 0027 for the
Type 2305, (AQ 0035 for the Type 2307) is connected between the
OVERLOAD AND FREQUENCY MARKING socket on the rear
panel of the 2010 and the REMOTE CONTROL socket on the Level
Recorder. The appropriate digit for marking may be selected on the
rear panel of the 2010.
Note: The cable for electrical drive of the 2010 is connected between
the X INPUT socket on the side panel of the 2307, and the FRE
-
QUENCY CONTROL VOLTAGE "In" socket on the rear panel of the
2010.
However the PAPER DRIVE FUNCTION selector on the 2307 should
not be placed in the "X-Rec." position.
9. Start the recording as indicated in point 5.
AC Recording
The dynamic range of the AC output is given in Table 6.2.
This indicates that it will normally be possible to employ any of the
Logarithmic Range Potentiometers with the Level Recorder.
