• The number of custom buffers (1 char) when x=1

• The custom buffer values, with sign and decimal point,

for each defined custom buffer (7 chars) when x=1

• The ID of the ISE electrode (2 chars) - if ISE available

when x=1 (HI 3221) or when x=2 (HI 3222)

• The molar weight of the selected ION, with sign and

decimal point (9 ASCII characters) when x=1 (HI 3221)

NSLxy Requests the number of logged samples (4 chars).

The command parameter (2 chars):

• x=1 request for channel 1

• x=2 request for channel 2

• y=P request for pH range when x=1

• y=M request for mV and Rel mV ranges

• y=I request for ISE range when x=1 (HI 3221) or

when x=2 (HI 3222)

LLSxy Requests the number of lots (information about lots) on the specified

channel and range (x - channelnumber; y - range number)

• xy = 11 - channel 1; range pH;

• xy = 13 - channel 1; range mV;

• xy = 22 - channel 2; range ISE;

• xy = 23 - channel 2; range mV;

The answer string contains:

• number of lots (3 chars)

• ID lot (3 chars)

• date (6 chars)
