Examples for offset- and slope-adjustment:
Example 1: Connecting a Pt1000-sensor (with an offset error depending on the cable-length of the sensor)
The device displays the following values (without offset- or slope-adjustment): 2°C at 0°C and 102°C at 100°C
Therefore you calculated: zero point: 2
slope:
102 – 2 = 100 (deviation = 0)
You have to set:
offset =
2
(= zero point-deviation)
scale =
0.00
Example 2: Connecting of a 4-20mA-pressure-transducer
The device displays the following values (without offset- or slope-adjustment): 0.08 at 0.00 bar and 20.02 at 20.00 bar
Therefore you calculated: zero point: 0.08
slope:
20.02 – 0.08 = 19.94
deviation:
0.06
(= target-slope – actual-slope = 20.00 - 19.94)
You have to set:
offset =
0.08
(= zero point-deviation)
scale =
0.30
(= deviation / actual-slope = 0.06 / 19.94 = 0.0030 = 0.30% )
Example 3: Connecting of a flow-rate-transducer
The device displays the following values (without offset- or slope-adjustment): 0.00 at 0.00 l/min and 16.17 at 16.00 l/min
Therefore you calculated: zero point: 0.00
slope:
16.17 – 0.00 = 16.17
deviation:
- 0.17
(=target-slope – actual slope = 16.00 - 16.17)
You have to set:
offset =
0.00
scale =
- 1.05
(= deviation / actual-slope = - 0.17 / 16.17 = - 0.0105 = - 1.05% )
9. Min-/max-value memory:
The device features a minimum/maximum-value memory. In this memory the highest and lowest performance
data is saved.
Calling of the minimum-value
press button 3 shortly
the device will display “Lo“ briefly, after that
the min-value is displayed for about 2 sec.
Calling of the maximum-value
press button 2 shortly
the device will display “Hi“ briefly, after that
the max-value is displayed for about 2 sec.
Erasing of the min/max values press button 2 and 3 for 2 sec.
The device will display “CLr“ briefly, after
that the min/max-values are set to the cur-
rent displayed value.
10. Serial interface:
The device features one
EASY
BUS
-Interface. You can use the device as a full function
EASY
BUS
-device. The
serial interface allows the device to communicate with a host computer. Data polling and data transfer is
done in master/slave mode, so the device will only send data on demand. Every device has a unique ID-
number that makes exact identification of each device possible. With the help of a software (like EbxKonfig –
freeware version available via internet) you are able to reassign an address to the device.
Additional accessories needed for the interface mode:
- Level converter
EASY
BUS
ó
PC: e.g. EBW1, EBW64, EB2000MC
- Software for communication with the device
EBS9M:
9-channel-software for displaying a measured value.
EASYCONTROL: multi-channel software for real-time-recording and displaying measure-values of a de-
vice in ACCESS®-database-format.
EASYBUS-DLL:
EASYBUS-developer-package for developing own software. This package features a
universal WINDOWS®-Library with documentation and program-examples. The DLL
can be used in any usual programming language.
