CHR n Change the instrument range according with the parameter

value (n):

 n=0 pH range/0.001 resolution

 n=1 pH range/0.01 resolution

 n=3 mV range

 n=4 Relative mV range

COMMANDS REQUIRING AN ANSWER

pH? Causes the instrument to send the pH reading. If the range is set

to mV, Err6 is received.

MV? Causes the instrument to send the mV reading. If the range is set

to pH, Err6 is received.

MR? Causes the instrument to send the relative mV reading. If the

range is set to pH or mV, Err6 is received.

TM? Causes the instrument to send the temperature reading.

RAS Causes the instrument to send a complete set of readings in

according with the current range:

 pH, mV and temperature reading on pH range.

 mV and temperature reading on mV range.

 Rel mV, absolute mV and temperature reading on Rel

mV range.

MDR Requests the instrument model name and firmware code.

PAR Requests the setup parameters setting (instrument ID, calibra-

tion alarm time-out, pH range, beep status).

GLP Requests the calibration data record.

Note:  Err8 is sent if instrument is not in measurement mode.

 Err7 is sent if mV are asked during pH calibration mode.

 NAK (21) character is sent when the instrument receives an

unknown or a corrupted command.

Note: Invalid commands will be ignored.
