Kbbbbb

Reads the measured values of all channels simultaneously. Notes:
1. 

R

  is an optional field, which is only transmitted when a reference is used. The [] are not transmitted, they

only depict the optional character of the field. It contains the measurement data of the activated reference
and consists of the following fields: 

 ±m.mmm

E

±ee

;

f

;

a

;

2. 

K

 contains the measurement data of the 47 channels and consists of 47 parts looking like this:

±m.mmm

[E

±ee

];

f

;

If a reference is used, the exponent field is not transmitted.

K

 contains no channel numbers, the data is transmitted in the order from channel 1 to channel 47.

Length of the response 

(including DA, without CR LF):

with reference:

(26 + 15 + 47 * 9   + 5) characters = 469 characters

without reference:

(26 +   0 + 47 * 13 + 5) characters = 642 characters

10.2.4 Measurement resolution

Response

DR

DR

cc

0.

mmm

E±ee

Reads the absolute resolution of channel 

cc

. Notes:

1.  This is the resolution of the active (displayed) measuring mode (mode 0 or 1)
2.  Depending on the actual resolution, 

mmm

 consists of 3, 2 or 1 digit

3.  The resolution is always given as an absolute value, even if measurement against reference is selected.
4.  Channel numbers R• and M• are only valid, if measurement against reference is selected. Otherwise the

response will be E02.

Example:
For the unit of measurement Gy/min the resolution of channel 17 in mode 1 (= dose rate) may be 50µGy/min,
displayed as 0.05 mGy/min.
Therefore, in mode 1 the response to DR17 will be  DR170.05E-03

10.2.5 Measurement unit

Telegram

Response

DU

DU

u

Reads the absolute unit of measurement of the active measuring mode. Possible values of 

u

:

when MULTIDOS is set to radiological units:

Gy  Gy/s  Gy/min  Gy/h

when MULTIDOS is set to electrical units: 

C     A

If the radiological unit is Roentgen, replace Gy by R in the upper lines.
