7.8 Information code types
MULTICAL® 803 constantly monitors a number of important functions. If a serious error occurs in the measuring
system or installation, a flashing “INFO” appears in the display. The ”INFO” field keeps flashing as long as the error is
present no matter which reading you choose. The ”INFO” field automatically disappears when the reason for the
error has been removed.
Note: Configuration of “Manual reset of info code” is not possible in MULTICAL® 803.
7.8.1 Information code types in display
In MULTICAL® 803, each digit of the info code is dedicated to one of the calculator’s inputs. For example, the second
digit from the left in the display is always related to information on temperature sensor t1. At the same time, the
info code is divided into sections so that a reading from left to right consists of: general information, temperature
information (t1, t2, t3, t4), flow information (V1, V2) and information about the pulse inputs A and B (In-A1/A2 and
In-B1/B2). See the table below for an overview of the info codes and response times.
Note: The temperature inputs t3 and t4 share info codes, which means that it only takes one event on one of the
inputs to trigger an info code. If, for example, just one of these two inputs are above the measuring range, the info
code will be “000
10000”.
