Start a calibration manually

1. Push MENU.
2. Select SENSOR MENU>APA6000 #1 APA
6000>CALIBRATION>EXECUTE CALIBRATION.
The analyzer completes any current measurement or priming cycle
before the calibration is started.
Note: A calibration typically takes 30–60 minutes to complete.

View the calibration history

1. Push MENU and select SENSOR MENU>APA6000 #1 APA
6000>CALIBRATION>CAL HISTORY. A list on the seven most
recent successful calibrations shows.
Note: The measured values of the standards are based on the previous
calibration curve.

Printer and computer formats

The analyzer can be configured to send measurement readings, alarms
and warnings to a printer or computer when a serial I/O module (SIO) is
connected to the analyzer. Refer to SIO1 (or SIO2) SETUP in Sensor
diagnostics in the maintenance manual. To send the data log to a
computer or printer, push MENU and select AQUATREND
MENU>PRINT DATA LOG.
Since the SIO can receive data from a maximum of eight analyzers, the
SIO channel shows in the first three characters. For example, " [1]"
identifies that the information is from the analyzer connected to SIO
channel 1.
[1]01/01/97 00:23: 3.234 S1P1
[1]01/01/97 00:23: 0.527 S1P2
[1]01/01/97 11:28: 3.977 S1P1 *W
[1]01/01/97 11:28: SMP1 OUT ALARM *A
[1]01/01/97 11:28: 0.611 S1P2 *A * W
[1]01/01/97 11:29: End SMP1 OUT ALARM *A
The first occurrence of any alarm or warning is sent out. The time/date of
the alarm or warning is printed followed by either "ALRM" or "WARN" to
identify that it is an alarm or warning. The specific alarm or warning is
then shown on the next line.
When the alarm or warning condition is corrected, the alarm/warning is
sent preceded by "END:" to identify that the condition is cleared. Some
alarms and warnings provide information only and do not have an end
(i.e., a fail to calibrate message is printed out only when the condition
occurs).
If an alarm or warning condition is active, then an "*A" for alarm or a
"*W" for warning is added to the end of the measurement readings.
RS232 commands
Table 1 shows the commands that can be sent from a computer through
the optional serial I/O module (SIO) to the analyzer for remote analyzer
operation. Table 2 shows the analyzer responses to valid and invalid
RS232 commands.
Terminate remote commands to the analyzer with a carriage return
character to identify the end of the command. Linefeed characters and
spaces are ignored. All incoming characters are converted to uppercase
before they are evaluated.
Always put the channel number before a remote command. For
example, if the analyzer is connected to SIO channel 1, send the remote
command 1SRT to restart the analyzer. The analyzer response is "OK"
and the SIO inserts the channel assigned for the analyzer (e.g., [1]OK).

Command Function
HLT Puts the analyzer in shutdown (standby) mode.
SRT Puts the analyzer back into operation.
CAL Starts a calibration at the end of the current cycle.
RCL=A Gets the calibration values for the last calibration. Add "=A" to recall
a maximum of 7 calibrations.
