11.3 Data telegrams
11.3.1 Read measured values
The response to a data telegram consists of various fields, separated by semicolons. The fields contain pa-
rameters and text.
The response to the D telegram is:
D

11.3.2 Description of parameters
m
Actual measuring mode. Valid values: 0
Þ
Dose or Charge, 1
Þ
Doserate or Current
ttttt.n
Elapsed measurement time. Consists of seven characters. Small numbers are right justified,
with leading spaces. Parameter n can have the values of 0 or 5.
If the maximum measurement time of 64800 seconds is exceeded, OL••••• will be transmit-
ted.
sss
Measurement status. Valid values: RES, STA, HLD, INT, RUN, NUL, ERR.
FL
Global flags. A two digit number, whose set bits, when converted to binary representation,
signal the following error:
.0
Þ
any channel is overloaded at the moment
.1
Þ
math error in any channel
.2
Þ
MULTIDOS data acquisition error
.4
Þ
overload in any channel since the start of a dose or charge measurement
.0 is the least significant bit
OO
Overload flags of the current status of the doserate or current measurement. 2 digit decimal
number whose set bits, when converted to binary representation, signal the following errors:
.0
Þ
channel 1
.5
Þ
channel 6
.0 is the least significant bit
OO
can take values from 00 to 63.
LL
Latched overload flags of the dose or charge measurement. 2 digit, whose set bits, when con-
verted to binary representation, signal the following errors:
.0
Þ
channel 1
.5
Þ
channel 6
.0 is the least significant bit
LL
can take values from 00 to 63.
MM
Math error flags of the actual measurement mode. 2 digit, whose set bits, when converted to
binary representation, signal the following errors:
.0
Þ
channel 1
.5
Þ
channel 6
.0 is the least significant bit
MM
can take values from 00 to 63.
R
Number of the rectum channel with the highest measured value.
R
can take values from 1 to 5
±m.mmm
Mantissa of the measured value. This field consists of six characters. Smaller numbers are
right justified, with leading spaces. Positive numbers use a space character instead of the
minus sign.
If the limits of representation (±999.9E+20) are exceeded, +0L••• or -0L••• will be transmit-
ted, depending on the sign.
E±ee
Exponent of the measured value. Two digit number, with leading zeroes if necessary. The sign
is always transmitted, either as + or -.
If the limits of representation are exceeded, •••• will be transmitted.
bbbbb
Block check sequence of the response. This is a five digit number, representing a 16 bit un-
signed integer, with leading zeroes if necessary.
The block check sequence is calculated starting from the first character of the response up to
the character preceding
bbbbb
and must be equal to the value of
bbbbb
.
