L4,
Confirmation of command.
20char
11-01-06 5
11:51:00,
Date, Day of week (1=Sunday), and time of recording
7-8char
10.44,
Reading with sign.
* Uncalibrated meter may respond with leading negative sign (ex.
-11.49) which extends the length of the string.
8char
023.8C,
Temperature in degrees C. Leading space replaced with negative sign
for negative temperature.
4char

0 = First logged record from initial connection to battery.
1 = Subsequent logged reading triggered by time interval.
Available on firmware feature 49 and above.
2char
,1
Available on models with snow LED.
0 = No snow data recorded.
1 = Snow data recorded.
Available on firmware feature 66 and above.
number
,1234567890
Available on models with snow LED.
Standard linear luminance value taken with the snow LED off. The
value is representative of the brightness (larger number = brighter).
The linear value is a compensated value of 150 times the period counts
or 45000 times the frequency, with a switchover point at determined
by the crossover selection mode on the report interval page.
7-8char
,9.72
Available on models with snow LED.
Snow reading in mpsas which was taken when the snow LED was on.
number
,1234567890
Available on models with snow LED.
Snow linear luminance value. The linear value is computed similarly
to the standard linear value described above.
last two Carriage return (0x0d), Line feed (0x0a).
