The interval for the data transmission (Int 2) determines the chronological
interval between automatic data transmissions. After the selected interval
expires, the current data record is transmitted to the interface. To set up the
transmission interval, press <RCL> while holding down the <RUN/ENTER>
key (display Int 2). Then, set the interval with <L> <M>.
Recorder (Analog output)
Via the analog output, you can transmit data to a recorder. Connect the
analog output to the recorder using the AK323/S interface cable.
The data output automatically switches to Recorder output.
Note
The output on the analog output corresponds to the value shown on the
display (pH 7.00 is output as 700 mV).
