5.4 Data Viewing
Store up to 500 data points in the meter memory. Use the
item in the meter Setup Menu to view the data
log points, active pH calibration log, active RmV calibration
log and active temperature calibration log.
The data log shows the most recent data log point first.
The meter will save up to 500 data log points and then
automatically overwrite the oldest data log point with the
newest data log point when the limit is reached. Each data
log point is saved with its associated date and time stamp.
To view the time stamp with seconds included, the data
log must be exported to a computer or printer.
The pH calibration log shows each calibration point and
the calculated slope value. Three, four and five point pH
calibrations will display the average slope value and then
the appropriate number of segmented slope values. The
RmV calibration log shows the RmV value with raw mV
value and temperature. The temperature calibration log
shows the temperature and offset value. Each calibration
log is saved with its associated date and time stamp. To
view the time stamp with seconds included, the calibration
log must be exported to a computer or printer.
Note: If desired, when in the View Logs item in the meter
Setup Menu, press the “Log/Export” key to export the
individual data log point or calibration log being viewed.
5.5 Data Exporting
Export data from the meter to a computer or printer. Use
the
item in the meter Setup Menu to set
the export type as computer or printer. If computer is
selected, logs are exported in CSV format. If printer is
selected, logs are exported in list format. Meter serial
communication protocol:

5.5.1 Remote Commands
Remote commands allow the meter to be interfaced with
computer software like LIMs and HyperTerminal. The
remote engine receives input from the serial port and
processes it. Commands sent to the remote interface will
be in the form of “OPCODE <OPERAND> CR”.
•
Only one command can be executed at a time. A
new command cannot be issued until the previous
command is done and prompt is given, shown as
the greater than symbol (“>”) followed by a space.
•
Empty commands (i.e. just a <CR>) will be ignored
and a new prompt will be issued.
•
<CR> (Carriage Return, ASCII 13) is used to
terminate a command. Whenever this character is
received, the internal buffer will be processed.
•
Remote commands are not case sensitive.
Remote Command: GETMEAS <CR>
Prints the current measurement immediately.
Remote Command: GETMEAS Data Count <CR>
Example: GETMEAS 2. Prints the current measurement for
a set number of times.
Remote Command: GETCAL <CR>
Prints all current calibration data. If no calibration is saved,
returns “>” to receive next command.
Remote Command: GETCAL MODE <CR>
Example: GETCAL PH. Prints the calibration data for
specific mode. MODE: PH or RMV.
Remote Command: GETLOG <CR>
Prints all logged measurement data. If no data is logged,
returns “>” to receive next command. Output format is
based on the Log Export Type setting.
Remote Command: SYSTEM <CR>
Prints the system information including meter model, serial
number, software version, date and time.
Remote Command: SETCSV <CR>
Sets the output format to Comma Separated Values (CSV).
Remote Command: SETKEYLOCK NUMBER <CR>
Example: SETKEYLOCK 1. Locks or unlocks the meter
keypad. NUMBER = 1 (lock) or 0 (unlock).
Remote Command: SETRTC YYYY-MM-DD-HH-
MM-SS-TIMEMODE <CR>
Example: SETRTC 2021-08-19-01-32-00-1. Sets the date
and time for the meter. TIME MODE = 1 (PM) or 2 (AM).
Remote Command: SETMODE MODE <CR>
Example: SETMODE PH. Sets the meter measurement
mode. MODE: PH or RMV.
Remote Command: GETMODE <CR>
Prints the active measurement mode.
