3.3 Manual interface: micro-switch, LEDs and rotary switches

In this section the manual instrument interfaces are described. In section 3.3.1 the micro-switch operation is explained (if present),

section 3.3.2 specifies the LED functionality and section 3.3.3 covers the rotary switch operation.

3.3.1 Micro-switch operation (single-channel versions only)

By means of manual operation of the micro push-button switch some important actions for the instrument can be selected or

started. These options are available in both analog and digital operation mode.

These functions are:

Reset alarm

Reset instrument (firmware program reset)

Auto-zeroing

Restore factory settings (in case of accidently changing of the settings)

Using digital RS232 or RS485 operation it is also possible to set:

Bus-address (only required for RS485)

Baudrate

Multi-functional switch

Status LED

Error/Warning LED

The tables below describe the micro-switch functions that can be started in normal operation mode and during power-up:

be cleared. During start-up the instrument will perform a (new) self-test.
