13.1 Introduction
The ELM can be operated depending on equipment by using the HART® interface.
In the following, the ELM operation and parameterization using the keypad are described.
The keypad is located in the electronic compartment and covered by an inspection window.
13.2 Display
The ELM has an integrated back lighted, alphanumeric display with two 16-character lines
(format 16 x 60 mm). Measurement data and settings can be read directly from this display.
The LCD display is designed be operated at temperatures ranging from − 20°C to + 60°C
(-4° F to 140°F) without incurring any damage. However, at freezing or near-freezing
temperatures, the display becomes slow and readability of the measured values is reduced. At
temperatures below − 10 C° (14°F), only static values (parameter settings) can be displayed.
At temperatures exceeding 60 C° (140°F), contrast decreases substantially on the LCD and
the liquid crystals can dry out.
