Operation
3.7.16 Cal at dSIR
Only for DSIR. Allows the user to calibrate directly at the DSIR.
The actual calibration is done at the DSIR. This is recommend-
ed for the first time the DSIR is connected to the Polytron 5000.
While in the menu, the Polytron 5000 acts as a display device
for the DSIR. The Up and Down arrows have no effect on the
reading while in this menu. See Instructions for Use Dräger-
Sensor.
3.7.17 Cal set 3-5 or stdy
Configuring the maintenance signal
The maintenance signal is transmitted on the 4 to 20 mA ana-
log output anytime the menu is accessed. It is user-selectable
between:
{
a steady 3.4 mA output signal
{
an oscillating 3 to 5 mA signal with a frequency of 1 Hz
3.7.18 SNR set dd LC dSIR
Configuring the sensor to be used
Polytron 5000 can use one of the following sensors:
1. DrägerSensor DD
catalytic bead sensor for 0 to 100 %LEL monitoring
2. DrägerSensor LC
catalytic bead sensor for 0 to 10 %LEL monitoring
3. DrägerSensor IR
infrared sensor for 0 to 100 %LEL monitoring
3.7.19 Pass set
Configuring the password
Only numbers 0 to 9 are allowed for the password.
The use of a password is optional on the Polytron 5000.
A password consists of a 4-digit number from 0000 to 9999; a
value of 0000 disables password protection and allows anyone
to access the menu.
To set/change the password, enter the function
z
the 4-digit LCD will show ‘0000’ with the first digit on the left
blinking
z
use the Up and Down arrows to increment or decrement
this digit, then tap OK
z
the second digit will blink; set the correct value using the Up
and Down arrows
z
repeat the process for the other two digits
z
tap OK when the full password is displayed
z
once a password is set, it has to be entered to gain access
to the menu.
3.7.20 LCD on or LCD off
This feature allows turning the LCD off in measurement mode,
effectively turning the Polytron 5000 into a non-display instru-
ment.
The functionality of the instrument remains active, indepen-
dently of the LCD state.
When in measurement mode and the LCD is set to OFF, press-
ing the Down arrow still gives complete access to the menu.
In case of an alarm, the red LED will blink. In case of a fault,
the yellow LED will lit and the display will toggle between ‘Err’
and a number.
CAUTION
The sensor used with Polytron 5000 has to be selected
in this menu item for proper linearization of the sensor
signal.
After changing the selected sensor, the instrument will
re-start.
When exchanging a sensor for a different type, the in-
strument must be calibrated.
