Keyboard operation
Control and indication parts
The front panel of the Multilogger includes 6 keys, 3 indication LED diodes
and a graphic display.

The red key with the switch symbol is used for Multilogger turning on/
off. The MIN/MAX keys (with the arrows) are used for quick show of the
minimal and maximal measured values and also for moving through
menu items. Function of keyboard upper row buttons is defined by actual
description of each button on the lower LCD line display.

The indication LED diodes inform us about the current state of alarms
and allows the operation personnel to observe this important information
even under low light and from a greater distance.
green LED
no active alarms, “everything
is OK
”
orange LED one alarm is active
red LED several alarms are active or a system alarm
(device malfunction)

The green LED (“everything is OK”) can be deactivated
in device
configuration to save energy. The indication LEDs can be enabled
permanently or can be set to a blinking mode in battery mode to save
energy also. If the measured quantity has both alarms set into the same
direction, the LED diodes will indicate the current level of value: green -
everything is OK, orange - exceeding the lower limit, red - exceeding the
upper limit.

The LEDs show an overview about all active alarms in the Multilogger. In
the device configuration, we can assign individual alarms to the LED
diodes for customizing the indication to our needs.
