5.
Select a chart paper for the Level Recorder. QP 1143 is recommended for logarith-
mic sweeps and QP 11 02 is recommended for linear sweeps.
6.
Carry out the instructions given in the Level Recorder Instruction Manual for posi-
tioning the pen/stylus over the starting point of the scan. For logarithmic sweeps
the starting point is at 20Hz, for linear sweeps it is arbitrary.
7.
Set up the required settings on the following controls of the Level Recorder:
POTENTIOMETER RANGE
RECTIFIER RESPONSE
LOWER LIMITING FREQUENCY
WRITING SPEED
PAPER SPEED (see also section 4.3 or 4.4).
8.
Select "Ext. Mech." on the 2010 SWEEP CONTROL.
A synchronised sweep of the frequency range can now be made according to the instruc-
tions for automatic single chart recording contained in the Instruction Manual for the Le-
vel Recorder. The synchronisation will also be maintained during reverse sweeps. If lin-
ear frequency scanning is required, see the additional information in section 4.1 .4.

Apart from the synchronising link, this configuration is similar in effect to the Mechani-
cal Link described above.

1. Connect the cable AQ 0034 (which is a cable connecting two 8 pin DIN plugs JP
0802, pin 1 to pin 1, pin 2 to pin 2, etc., Fig.4.8) between the X-INPUT socket on
the Level Recorder and the FREQUENCY CONTROL VOLTAGE
"In"
socket on the
rear panel of the 2010
.
2. On the 2010 set SWEEP CONTROL TO "Manual" and COUNTING TIME is "1 s",
and adjust the pointer on the frequency scale to "0,02 kHz" on the logarithmic
scale.
3. With the FREQUENCY INCREMENT potentiometer on the 2010 in its middle position
so that the centre light is illuminated, adjust the FREQUENCY ADJUSTMENT poten-
tiometer with a small screwdriver until the Nixie display indicates "0,0200 kHz".
4. Set the SWEEP CONTROL on the 2010 to "Ext. Volt.", and insert the required
