It is also possible to remotely control the instrument with any
terminal program. Use HI 920010 cable to connect the instrument to
a PC, start the terminal program and set the communication options
as follows: 8, N, 1, no flow control.

To send a command to the instrument, follow the next scheme:
command>
This line makes the computer send a Data Link Escape character, the
command expressed as a 3-character sequence and a CR character.
Note: All the terminal programs that support the ANSI escape
sequence, represent the DLE character by the string '^P' and
the CR character by the string '^M'.

pH?
Causes the instrument to send the pH reading ("Err 1" is sent
if out of range). If the range is set to mV, "Err 6" is sent.
MV?
Causes the instrument to send the mV reading ("Err 2" is sent
if out of range). If the range is set to pH, "Err 6" is sent.
TM?
Causes the instrument to send the temperature reading
("Err 3" is sent if out of range).
Notes: • Either small or capital letters can be used.
• The characters sent by the meter are always capital letters.
• A “CAN” character (ASCII Code 24) is sent when the
instrument receives an unknown or a corrupted command.
Note: Invalid commands will be ignored.
The temperature has an effect on pH. The calibration buffer solutions
are affected by temperature changes to a lesser degree than normal
solutions. During calibration the instrument will automatically calibrate
to the pH value corresponding to the measured or set temperature.
During calibration the instrument will display the pH buffer value at
25 ºC.
