•####.#
Ratio of measured value of channel 2 divided by the measured value of channel 1, given in
percent. The decimal point position is fixed. Smaller numbers are right justified, with leading
spaces. Positive numbers use a space character instead of the minus sign.
If the maximum representable ratio of ±9999.9 is exceeded, •####.# will be transmitted.
If one of the measured values exceeds it limits of representation, •----.- 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
.
7.2.3 Read maximum value
The response to the DMc telegram is
DMc•m.mmE±ee
where c is the channel number (valid values are 1 or 2). The transmitted value is the maximum value of the
doserate / current measurement for the active unit (radiological or electrical) and actual measuring range of that
channel. The value is formatted in scientific notation.
7.2.4 Read Resolution
The response to the DRc telegram is
DRc•0.mmmE±ee
where c is the channel number (valid values are 1 or 2). The transmitted value is the resolution of the actual
measuring mode for the active unit (radiological or electrical) and actual measuring range of that channel. The
number of digits following the decimal point may vary from 1 to 3.
