Connecting analogue sensors
Connector pinning, view to
the plug at DS 300-P
Analogue sensors such as Pt100, Pt1000 (3-wire), 0-20 mA, 4-20 mA, 0-1 V and 0-10
V types can be connected to the analogue inputs (no. 3-6) of DS 300-P4 and P6.
Please refer to the connection chart and the connector pinning above. For loop pow-
ered sensors, DS 300-P can supply current of up to 25 mA. For signal connection the
optional 5 m cable 0553 0110 can be used, which comes with connector and open wire
ends.
In the next step, these sensors have to be programmed in DS 300-P. Please select
from the menu “Sensor Settings” - “Terminal 3:” - “Select sensor type”. Choose from
the predefined types the correct one. Attentions: the predefines types will measure the
process signals and display them as they are in Ma or V. If a scaling to the original
physical value and unit is desired, we recommend to download a small tool (DS 300-P
Sensor Configuration) from our web page, which enables users to define their own sen-
sor types (www.cs-instruments.com.hk). When using the DS 300-P sensor configura-
tion software it’s recommended as a first step to read out the current sensor settings.
Remark: 5 m connection cable with open wires (P/N: 0553 0110) have 5 cores. These
5 cores match with the pins of DS 300-P plug one-to-one, which is showed above.

Operation in detail
By pressing the <Enter> key the menu can be accessed. DS 300-P has following main
menus:
Logger operation
Sensor settings
System status and setting
For CS dew point sensors following settings are available:
 Set moisture unit: (ºCtd, g/m3, g/kg, ppm etc.). Attention: g/m3, mg/m3, ppm[V]
and atmospheric dew point require to enter a reference pressure.
 Set reference pressure: required for g/m3, mg/m3, ppm[V] and atmospheric
dew point calculation. The pressure has to be entered as absolute pressure (not
gauge pressure!)
For the unit atmospheric dew point and ppm[V], the line pressure (absolute)
has to be entered.
For the unit g/m3, mg/m3, if the calculate should be done under line pressure
conditions, a reference pressure of 1013 hPa has to be entered.
If the calculation should be done for atmospheric conditions, the line pres
sure (absolute) has to be entered.
Dew point sensor settings
DS 300-P has up to 4 analogue input channels at terminal 3 to 6. These channels
don’t have an automatic sensor detection, the sensors need to be manually selected.
Following settings are available:
 Select sensor type: Ds 300-P stores up to 15 different analogue sensors which
can be selected from the list
 Show setting: the details of the sensor settings such as: sensor type, unit, reso-
lution, input scaling and calibration offset can be viewed
 One point calibration: The instrument provides a one-point system calibration,
which can eliminate accuracy failures of instrument and sensor. If an accurate
reference is available (i.e. Calibration Lab), the system can be calibrated at one
point to this reference. The calibration is stored inside the DS 300-P. However
this calibration offset is applied to every sensor connected to this particular ter-
minal. If the sensor type is changed, DS 300-P will delete the stored calibration
offset.
 Remove one-point calibration: is used to delete the calibration offset

Logger operation Sensor settings
DS 300-P includes a data logger that can record up to 1,000,000 measurement values.
In order to configure the logger function and to activate/deactivate it, there are several
functions available which are explained below:
Set logging rate and
averaging option The logging rate defines the interval data should be recorded in
the memory. It will record from every activated channel a sam-
ple. The averaging option can be used to calculate an average
value. I.e. DS 300-P is measuring every 1 second and if the
logging rate is 10 seconds, it will calculate an average value
out of the last 10 measurement values and store it as a re-
corded sample.
Key start/stop log-
ging Starts or stops the data recording. Whenever a new recording
is started a new file is created in the memory.
Select logging
channels Those channels which should be recorded with the data logger
must be selected first. For example, if Flow is selected to be
recorded the flow value of all connected flow sensors will be
recorded. Attention: sensors connectable on port 3...6 are
shown as they have been selected in the sensor setting menu.
Set logger memory
mode It can be selected to stop logging when memory is full, or the
“wrap around mode” can be chosen, which then will overwrite
the oldest values as soon the memory is full.
Show logger memory Informs about the current protocol:
- number of channels programmed for logging
- number of values stored per channel
- how many values still can be recorded
- the estimated logging time
- memory status. Start/stop conditions
Set time start
condition DS 300-P can be programmed to start at a certain time. Pro-
grammed time must be 10 seconds later than the system time.
View protocol Single protocols (files) can be viewed. DS 300-P will show the
available protocols with date, number of channels, number of
recorded values per channel and min, max and mean values.
Delete protocol Single protocols (files) can be deleted. DS 300-P will show the
available protocols with date, number of channels and number
of recorded values per channel.
Format logger This function is used to free all memory of DS 300-P. It should
be used with care, as recorded protocols will be erased per-
manently.
The following chapter describes the settings related to the sensor itself, which can be
changed on the DS 300-P menu. For that purpose select in the menu the function
“Sensor settings”.
After the selecting “Sensor settings”, the next screen will show all detected flow/dew
point sensors of terminal 1 and 2 and the selected analogue sensor of terminal 3 to
6. Changes can be done individually for each sensor, by selecting the terminal where
the sensor is connected to.
The next chapters describe the available settings of the different sensors.
For CS flows sensors following settings can be made:
 Set tube diameter: for flow calculation
 Set total consumption: counter can be set to any value
 Set flow unit: Selection of the desired flow unit
 Set consumption unit: selection of the desired consumption unit
 Set reference pressure: in order to calculate the standard flow
 Set reference temperature: in order to calculate the standard flow
 Set gas type: Select the gas which is measured with the flow sensor.
Note:
Reference pressure and reference temperature are not related to the actual process
pressure or temperature. They are used to calculate the standard flow at standard
conditions, for example: 1000 hPa, 20 ºC.

Connecting analogue sensors
Connector pinning, view to
the plug at DS 300-P
Analogue sensors such as Pt100, Pt1000 (3-wire), 0-20 mA, 4-20 mA, 0-1 V and 0-10
V types can be connected to the analogue inputs (no. 3-6) of DS 300-P4 and P6.
Please refer to the connection chart and the connector pinning above. For loop pow-
ered sensors, DS 300-P can supply current of up to 25 mA. For signal connection the
optional 5 m cable 0553 0110 can be used, which comes with connector and open wire
ends.
In the next step, these sensors have to be programmed in DS 300-P. Please select
from the menu “Sensor Settings” - “Terminal 3:” - “Select sensor type”. Choose from
the predefined types the correct one. Attentions: the predefines types will measure the
process signals and display them as they are in Ma or V. If a scaling to the original
physical value and unit is desired, we recommend to download a small tool (DS 300-P
Sensor Configuration) from our web page, which enables users to define their own sen-
sor types (www.cs-instruments.com.hk). When using the DS 300-P sensor configura-
tion software it’s recommended as a first step to read out the current sensor settings.
Remark: 5 m connection cable with open wires (P/N: 0553 0110) have 5 cores. These
5 cores match with the pins of DS 300-P plug one-to-one, which is showed above.

Basic concept for MENU mode key operation
- use these keys to browse and select different items in menu, and scroll
through different pages of measurement value display
- use these keys to alter or adjust the setting option or numbering
- use this key to exit the current menu level
- use it to leave all setting state, without saving the change
- use this key to enter to submenu or next menu level of the current
selected menu item
- use it to confirm the setting change or enable an option in all setting
state
Typical menu display layout and keys description :
The current select menu
item will be shown in nega-
tive color.
If there is a “ < ” sign, it
means we can exit the cur-
rent menu or go up one
level from the current menu
level.
If there is a “ > ” sign, it
means we can go into the
submenu of the current
select
Selectable menu item, it
shows 4 items at a time. If
the total items in the current
menu level is more then 4
items, the menu item should
scroll over.
It tells how many item exist in
the current menu, and which no.
of item is currently selected
