To obtain a printout
of
the output from the
2512
on the Alphanumeric Printer Type
2312,
carry
out the following procedure:
1.
Connect the two instruments together via the digital interface sockets on the rear
of
the
instruments using the interface cable AO 0194 (AO 0184 if the Alphanumeric Printer is
an
earlier type).
2.
Set the INTERFACE MODE SWITCH on the rear panel
of
the printer to the "IEC - Listen
Always" position.
3.
Set the leftmost
of
the two PRINT switches on the front panel
of
the printer in the "Time &
Data" position (up),
or
in the data only position (mid), as required, and the rightmost
switch
in
the
"Auto"
(up) position.
4.
Turn the CLOCK CONTROL SELECTOR on the front panel of the printer to either:
or:
"Ext."
One
of
the "Print Intervals"
"1 h", "30 min", "15 min",
"5
min", "1 min", "20 s",
or
"10
s"
In
which case the print interval will be controlled by the
2512
and a new set
of
values will be printed out every
six seconds if subswitch number 7
of
the ADDRESS
SWITCH on the rear panel of the
2512
is set to "Print-
er", or every 2 seconds if the switch is set to
''Calculator''.
In
which case the print interval will be controlled by the
internal clock of the printer at the preset value.
5.
Set the first three subswitches (numbered
8,
7,
and
6)
of
the ADDRESS SWITCH on the
rear panel
of
the Type
2512
as
follows:
Subswitch 8 should be set to
"O:
Accumulate" to continue the mea-
surement after each data readout and thus accumulate
data,
or
to "1: Reset" if the
2512
is to be reset at each
readout and a new measurement period is to be
begun.
