7.2 Data telegrams
7.2.1 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:
Dm;ttttt.ns;sss;FL;O;L;M;±m.mmmE±ee;a;±m.mmmE±ee;a;·####.#;bbbbb
The measured values and resolution indicators are that of the actual measuring mode and are transmitted
channel 1 first, followed by channel 2. The ratio is always transmitted, even if absolute values are displayed
(see below).
7.2.2 Description of parameters
mActual measuring mode. Valid values: 0 ÞDose or Charge, 1 ÞDoserate 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 Þany of both channels is overloaded at the moment
.1 Þmath error in any channel
.2 ÞMULTIDOS data acquisition error
.3 ÞMULTIDOS HVerror at the moment
.4 Þoverload in any of both channels since the start of a dose measurement
.5 ÞMULTIDOS HV error since the start of a dose measurement
.0 is the least significant bit
OOverload flags of the doserate / current measurement. One digit, whose set bits, when con-
verted to binary representation, signal the following errors:
.0 Þoverload in channel 1
.1 Þoverload in channel 2
LLatched overload flags of the dose / charge measurement. One digit, whose set bits, when
converted to binary representation, signal the following errors:
.0 Þoverload in channel 1 since the start of a dose measurement
.1 Þoverload in channel 2 since the start of a dose measurement
MMath error flags of the actual measurement mode. One digit, whose set bits, when converted
to binary representation, signal the following errors:
.0 Þmath error in channel 1
.1 Þmath error in channel 2
±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.
aResolution of the measured value. One digit. Valid values:
2 Þresolution below 1% (conforming to ** on the measuring screen)
1 Þresolution below 0.5% (conforming to *)
0 Þresolution is 0.5% or better
