(3) Press the RESET button again within 3 seconds of releasing it and hold until
the required calibration is displayed [

table below].
(4) Release RESET button when the desired type of calibration is displayed.
(5) For details of the calibration procedure [

chapter 5.3].
12.7 Relay Connections
All electrical connections to the internal relays can be made directly on the printed
board [

Figure 7]. When connecting the relays to motors, fluorescent lamps or
other inductive loads, it is necessary to suppress any sparks or inductive feedback
that may occur at the relay contact. These effects may damage the instrument and
make it inoperative.
One way to reduce these effects is to install a “Quencharc”, available from MSA as
part number 630413, across the load being switched.
The RESET function can also be executed by an infrared command
from the ULTIMA/ULTIMA X Series Controller
[
