Maintenance Inspection
Quarterly Inspection9-2.
Check the following points every three months.
If any trouble is detected, indicate on the unit that it is out of order and contact your local Atom representative
immediately.
Item to check Procedure Description
Servo control
Set the skin temperature to 36.0°C
in the ser vo control mode, and
warm and cool the skin temperature
probe.
Warm the skin temperature probe and check that
the number of bars on the heater output indicator
decreases when the displayed skin temperature is
36.0°C or higher and increases when it is below
36.0°C.
Set temperature
alarm
*
Set the skin temperature to 36.0°C
in the ser vo control mode, and
warm and cool the skin temperature
probe.
Check that the set temperature alarm indicator
comes on and an audible alarm sounds when
the displayed skin temperature deviates from
36.0°C±1.0°C or 36.0°C±0.5°C.
Set heat alarm
Set the heater output to 100% in the
manual control mode, and warm the
skin temperature probe.
Check that the set temperature alarm indicator
flashes and an audible alarm sounds when the
displayed skin temperature becomes 40°C or
higher.
Baby check alarm
Set the heater output to 100% in the
manual control mode.
Check that the baby check alarm indicator comes
on and an audible alarm sounds in 15 minutes.
* Either the set temperature ±1.0°C or the set temperature ±0.5°C is selectable for the temperature devia-
tion limit at which the set temperature alarm will occur. Check that the set temperature alarm occurs when
a detected skin temperature deviates from the selected deviation limit.
Periodical Replacement Parts9-3.
Periodical replacement parts are those which gradually deteriorate and wear down with use. They need peri-
odical replacement to keep the accuracy and performance of the unit at a proper level. Timing of replacement
varies with the frequency and conditions of use. Consult your local Atom representative for replacement.
