Gas type correction
factor
For total pressure gauges employing a measuring method which is dependent on the
type of gas, a correction factor can be assigned to the gauge. This will ensure, for a selected gas, the pressure display is corrected in a broad pressure range. On a combigauge such as the HPT 200 and the MPT 200 with two different measurement methods
two correction factors are necessary (see the operating instructions for the gauge).

Re-adjusting For zero adjustment, ensure the pressure in the vacuum chamber is at least one decade
below the measuring range of the gauge and is not subject to large pressure fluctuations.
Bring gauge up to operating temperature (≥ 5 minutes).

Press set key until the cursor flashes at the parameter ad-
just.
Press the Up-key; HI is displayed at the cursor position.
Note: Within the limits of 800 to 1200 hPa the gauge can be ad-
justed to atmospheric pressure.
After pressing the set key the display shows the preset ref-
erence value (*)/(**).
Set the actual atmospheric pressure with the Up-/Down
keys (**).
By pressing the set key the new value is taken into account,
and the cursor jumps back to the channel number ch.
Successful adjustment is prompted by o.k.; if not o.k. is dis-
played the gauge could not be adjusted.
Set the zero adjustment LO in the same way.
Note: When adjusting zero LO, ensure that the reference pres-
sure in the vacuum chamber is at least one decade below the
measuring range of the gauge.
(*) The reference pressure can only be entered in the measurement units mbar, hPa or Torr. If, for
example the unit bar is selected, for reference pressure input purposes there is a temporary switch
over to mbar, with mTorr to Torr and with Pa to hPa. When adjustment has been completed the originally selected pressure unit is again active.
(**) These points are only required for atmospheric pressure adjustment of CPT100/200 and the
RPT100/200.

Sensor menu Total pressure gauges with hot cathode sensor (e.g. HPT 200 ) may need baking in ultra
high vacuum to desorp the gasload from surfaces. The degas process lasts for three
minutes by default but can be stopped manually at any time. Pressure reading with re-
duced accuracy is possible during degas, the PRESSURE menu shows degas for the
concerned channel as long as the operation proceeds.
In the sensor menu the type dependent functions of the combination gauges RPT 100/
200, HPT 100/200, and MPT 100/200 can be selected. The settings are described hereunder taking the HPT 200 as an example.
SENSOR MENU
The high vacuum sensors of the combined gauges HPT 200
and MPT 200 can be switched manually:
– BAFil = Filament of the BA sensor
– CCSens = Cold cathode sensor
Press set key until the cursor flashes at the parameter BA-
Fil; the status of the function will be displayed (On or Off).
Switch filament On or Off using the Up/Down keys.
Confirm with set key.
For the HPT 200 gauge the value in brackets define the selected filament:
Select 1, 2 or auto.
Confirm with set key.
If auto is selected, an automatic switchover to the other filament
takes place when necessary (in case of wear).
For the MPT 200 gauge CCSens appears instead of BAFil.
Switch sensor on or off using the Up/Down keys.
Confirm with set key.
Select switching mode for combination gauges:
Press set key until the cursor flashes at the parameter
SwMode; the status of the function will be displayed
(trans_Hi, trans_Lo or switch, depending on the type of
gauge).
Use Up/Down key to select the desired function.
Confirm with set key.
Activate the degas function:
The function degas is only possible for total pressure gauges
with hot cathode sensor (HPT 100/200).
Press set key until the cursor flashes at the parameter de-
gas. The status of the degas function will be displayed (
or On).
Use the Up key to select degas On.
Start the degas process with the set key.
The degas process can be manually deactivated at any time by
switching the degas function to Off:
Press the set key until the cursor flashes at the parameter
degas.
Select the function Off with the Down key.
Switch off the degas process with the set key.

After selection of this menu via the Menu key the cursor flashes
on the position rel: (relay number).
Select the required relay number with the Up/Down keys.
Confirm relay number with the set key.
Assign channel number with Up/Down keys at the parame-
ter chann:
– ch1/ch2: Relay switches according to the pressure value of
the selected channel.
– off: Relay switches off independently of the set/actual com-
parison.
– on: Relay switches on independently of the set/actual com-
parison.
Confirm channel setting with set key.
Note: Each relay can be assigned to each of both gauge chan-
nels. It is also possible to link both relays with only one channel.
Alter the required set point with the Up-/Down keys in the
menu press.
Confirm set point with set key.
Proceed in the same manner for the parameter hyst.
Note: The hysteresis is asymmetric to the set point, i.e.the relay switches on at the set point and off at set point+hysteresis.
Altering the set point will cause the related hysteresis to be
matched automatically by a percentage relation to the new set
point. The preset value can be altered at will.
Example
Previous setting SP1:
– press = 20 hPa (set point "on" 20 hPa)
– hyst = 2 hPa (set point "off" 22 hPa)
new set point SP1:
– press = 400 hPa (set point "on" 400 hPa)
– hyst = 40 hPa (set automatically to 10 % of the threshold
value)
