１ Periodic Inspections
In order to maintain accurate performance of the APM-7 and to guarantee safe oparation of the
device, periodic inspections must be performed at regular intervals.
１.１ Cleaning of Test Cup and Test Cover
Caution: Do not bend the tip of the flash detector when cleaning test cover.
If the tip of the flash detector is bent, sensitivity deteriorates and
thus flash detection may be missed.
(1) Clean Test Cup using some solvents if there is some deposit in the cup. Use wire brush if the
deposit can not be removed by solvent. Wrong results may be obtained if some deposit in
the cup.
(2) Clean Test Cover using some solvents once in a week. If some sample sticks to the test
cover, the function of the shutter and ignition source application may be wrong, and it causes
wrong results. Clean the cover using some solvents by pushing arm rod which is for manual
application. Dry the cover well before the next test.
１.２ Confirmation of temperature correction value
(once per month)
Confirm temperature correction value is right or not by the procedure described in section ２.３.
３.
１.３ Confirmation of displayed temperature
(perform once per 3-months)
Confirm displayed temperature is agree with mercury thermometer or not by the procedure
described in section ２.３.１to ２.３.３.
１.４ Gas Leak Inspection
(once per 3-month for outside and once per year for inside the tester if using gas ignition)
・ Warning： Never touch the ignition coil and/or any electric components of
the equipment when performing gas leak inspection. Touching
any of the above components may cause serious burns or
electrical shock, as the unit is powered during gas leak
inspection.

２ Adjustments
Adjustment of Indicated temperature correction, Initial heat value and some another parameter is
done by pressing panel keys. The operation procedure is as follows.
Press the FUNCTION key and RESET key, then consecutively release the RESET key and then
the FUNCTION key. The following MENU Screen will appear.
Fig. 3 MENU Screen
By pressing Right-Left key to select item, then press FUNCTION key to display each setting
screen. For the changing value, press Right key to blink the first character, then press Right-Left
key/ Up-Down key. Press RESET key after setting is completed.
Record changed value to “Appended Table 1 APM-7 Setting Table”. It will be required when
built-in battery goes dead (approx. 5 to 7 years).
２.１ Filament Output Settings
Caution: Adjust filament output when a new igniter is installed. If
filament output value is high, the electric ignitor may be burnt
out in a short time.
Tanaka Scientific Limited will not be liable for burnt out
igniter, if appropriate adjustment was not carried out by the
user.
Each piece of igniter has a slightly different resistance and thus when a new piece is installed
supplied electric power needs to be adjusted. For the replacing procedure, see 4.2.5 on page 34.
Press Right-Left key to select Filament (blinking) from the MENU Screen, then press
FUNCTION key. The following Filament Output Setting Screen will appear.
Press Right-Left key to select Set output (output value is blinking), then change the output
value by pressing Up-Down key. The provisional values are as follows. If the AMP-7 is now in
