Hydran* M2-X Instruction Manual
MA-029 Rev. 1.0, 30-Jul-18
Both the display and keypad are designed to function under an extremely wide
temperature range.
Note: It is recommended to use the Perception software rather than the Hydran
M2-X’s user interface (keypad and display; see Figure 3-1); Only the analog I/O
calibration and communication parameters cannot be accessed with the Perception
software. All other parameters and commands can be accessed both with the Hydran
M2-X’s user interface and the Perception software.
3.1.1 Using the Keypad Keys
3.1.1.1 Three Context Keys
The purpose of each of these keys can change according to the screen content.
Their purpose is displayed on the bottom line of the display, directly above the keys
(for an example, see Figure 3-2). A key that is not used will have no bottom line text.
A specific function is always assigned to the same context key. The Table below
shows examples of common context keys in the Main Display mode (see
Section 3.1.2.3).

Table 3-1: Examples of Common Context Keys
3.1.1.2 Four Arrow Keys
These keys are used as follows:
• They are used to navigate through options in a menu, parameters in a list or
digits of a parameter value. When an item is selected, it is displayed in white
on a black background. Use the arrow keys to select other items on the
screen: the Up arrow goes up, the Down arrow goes down, etc.
• When changing the value of a parameter, the Up arrow increments the value
of the selected digit and the Down arrow decrements it. Press and hold these
keys for more than one second to accelerate the rate of increase or decrease.
