Operation

Dräger Polytron 5000 9

3.6.2 Gas conc

Displays the current value of the concentration of the target

gas in ppm. This field is read-only, and cannot be modified by

the operator.

3.6.3 Password

The use of a password is optional with the Polytron 5000. A

password consists of a 3-digit number from 000 to 999; a value

of 000 disables password protection and allows anyone to

access the software interface. The instrument is delivered with

the password set to 000.

If a password has been set, it must be entered to gain access

to the software menu. Tap the magnetic wand over the Down

arrow until the ‘PAS’ menu item is displayed. The 3-digit LCD

will then show ‘000’, with the first zero on the left blinking. Use

the Up and Down arrows to increment or decrement this digit,

then tap OK. The second (middle) digit will blink, and the

correct value should be set using the Up and Down arrows as

before. Repeat the process for the third digit. Tap OK when the

full password is displayed. If the displayed value matches the

set password, you will gain access to the rest of the menu. If

an incorrect password is entered, the instrument will return to

the measurement mode.

3.6.4 Password adj

Use the Down arrow to scroll to the last menu item, Password

Adjust. The display will show the message ‘PAS’, ‘ADJ’, ‘000’.

If a password other than 000 has already been entered, that

number will appear in place of ‘000’.

Tapping the magnetic wand over OK causes the 3-digit display

to flash. Tap the Up or Down arrows to scroll the value to the

desired new password. The display will stop scrolling at a

maximum value of 999 or a minimum of 000; it will not roll over.

Tap OK when the desired password is displayed to accept this

as the new password. Once a password is set, you will have to

enter it to gain access to the menu.

3.6.5 Zero adj

Allows you to adjust the zero reference point of the sensor

when no target gas is present, such as during calibration (

see

Section 4.1 on Page 10).

3.6.6 Span adj

Allows you to adjust the displayed gas concentration to match

the known concentration of an applied calibration gas. For

example, if a 100 ppm calibration gas is applied to the sensor,

the Span Adj value should be adjusted to 100 once the sensor

reading has stabilized (

see Section 4.1 on Page 10).

3.6.7 FSD adj

Permits adjustment of the Full Scale Deflection, or range, of

the instrument. It establishes the upper limit value of the

4-20

mA output of the sensor. For example, if the FSD is set to

100

ppm, then 0 ppm of the target gas will produce a 4 mA

output, while 100

ppm will produce a 20 mA signal.

3.6.8 A1 adj
