P26 Instruction Manual

Menu (optional)
If the P26 includes a display, you can use the menu to adjust various settings. Press the Menu
key to bring up the menu.
In Menu mode, the parent menu item always appears in the top display line. The middle line
always shows the current sub-menu item or value to be changed. The bottom line displays units
or other help texts.
Start the Menu mode by pressing the "Menu" key. It can be protected with a four-character
password.
At the main menu level, “Menu” is displayed in the top line and “Display” in the
middle line. Select your desired sub-
menu by pressing the “▲” and “►” keys. Press “Enter” to
go to a sub-menu or enter a value.
Press the “Menu” key to go to the next menu level or to stop
entering values.
7.1 Display
The display unit can be selected with this menu item.
Press the “▲” and “►” keys to select the
unit you want and press “Enter” to confirm. The type of display (pressure, flow rate etc.) is
selected automatically.
When the air consumption function is activated, the selection of units that can
be displayed is limited to the following: m³/s, m³/h, ft³/h, kg/s, kg/min or kg/h.
7.2 Scale
The scaling function is not available when the air consumption function is
activated. Entering the scaling values defines the density of the medium.
Changing these values when the air consumption function is activated will result
in the calculation of incorrect totals.
The P26 is usually supplied with standard measuring ranges. You can use the scale to adjust
the measuring range for your own use. The output voltage or currents are then copied to this
scaled range.
The scaled range should always be more than 0.1 times of that of the P26’s
measuring range, because otherwise the resolution of the outputs and the accuracy will be
poorer.
With this menu item, there are 4 sub-menu items:
Pressure
Volume flow
Mass flow
Flow rate
