7.4.3 Password
The use of a password is optional. A password consists of a
4-digit number from 0000 to 9999. The value 0000 disables
the password protection and allows anyone to access the
menu.
Information on changing the passwords can be found in 11.1.
Applies to the Polytron 57x0 IR:
If "PIR LOCK" is enabled on the PIR 7x00, this replaces the
password on the Polytron 57x0 IR. For information on
enabling the "PIR LOCK" function, refer to section 13.3.4.
7.4.4 Opening menus
● If the password is disabled
a. Tap [DOWN] and navigate to the relevant menu item
● If the password is enabled
a. Tap [DOWN].
"0000" is displayed and the first zero flashes.
b. Tap [UP] / [DOWN] to increase or decrease this
number, then tap [OK].
The second digit flashes.
c. Repeat the process for the remaining digits and tap
[OK].
If an incorrect password is entered, the instrument
returns to measuring mode.
7.4.5 Modifying parameters
1. Navigate to the relevant menu item and tap [OK].
The current value or status flashes.
2. Use [UP] / [DOWN] to set the desired value and tap [OK].
The setting is saved. The menu is displayed again.

During adjustment, the measurement accuracy of the sensor
is checked and adjusted with a known test gas concentration.
First the zero-point of the sensor is adjusted, and then the
sensitivity. Adjustment must be performed on a regular basis.
The length of the adjustment intervals depends on the
ambient conditions in which the sensor is operated.
Ambient conditions and aging results in sensor drift. Sensor
drift reduces the display accuracy of measured gases.
Adjustment restores this display accuracy. Shorter adjustment
intervals must be selected depending on the extent of the drift.
To gauge the ambient conditions for new installations,
selecting short adjustment intervals and documenting the drift
is recommended. The system operator should define the
adjustment interval length with the aid of the collected data.
Under normal conditions, Dräger recommends the following
adjustment intervals
– Electrochemical sensors (EC): 6–12 months
– Catalytic sensors (CAT): 3–6 months
– Infrared sensors (IR): 6–24 months
