PEAK FUNCTION
The instrument continuously memorises the peak value of the gross weight.
This function is available only if the peak calculation function is enabled via the corresponding parameter
in the set-up menu of the instrument. The peak display is shown by the letter P on the left of the display.
The peak value is detectedat the same frequency of acquisition of the weight (see table on filters). The
peak value can also be used for the following functions:
FUNCTION DESCRIPTION
LOGIC OUTPUTS
The set-points can be set to have the peak value as a reference. (See the
procedure for setting operation of the logic outputs).
SERIAL PORT
Acquisition of the peak value (peak hold) using the CONTIN, AUTO, DE-
MAND, and MODBUS SLAVE protocols.
ANALOGUE OUPUT The analogue ouput value can assume the peak value (peak hold). (See the
analogue output configuration procedure).
FREEZING THE ACQUIRED WEIGHT
You can freeze the weight in the face of a variation of the logic inputs, if any of these is set in the
HOLD mode.
TEST FUNCTIONS - RS232 AND RS485
The test consists of sending the string received from its serial line (echo) and the display of the number
of strings received and the number of characters received in the last string.
00C= 00
TEST FUNCTIONS - ANALOGUE OUTPUT TEST
Once in the test out function
out. An
, , the following message will appear:
out 0 out 0 where 0 indicates the output value (in current or voltage based on that selected) ex-
pressed as a % of the full scale.
You can change this value from 0 to 100, with an interval of 10%, by pressing the UP key.
Press the ENTER key to exit the function.
INPUT / OUTPUT TEST FUNCTIONS
Once in the IN OUT test function, the following 1n 00 1n 00 will appear where 00 depends on
the logic inputs mode, as shown in the table:
VALUE MEANING
00
No active input
01
Input 1 active
10
Input 2 active
11
Inputs 1 and 2 active
In the same menu you can enable or disable the outputs by repeatedly pressing the UP key .
The status of the two outputs is shown by the first 2 status LEDs.
Press the UP key to exit the function.
