Actuator Heat Block Temperature

The actuator heat block temperature should be checked once a month to verify that
it is 37°C ± 0.5°C. The ACT Plus™ instrument records all temperature adjustments
into its temperature log.

Verification with Thermometer

1. Turn the ACT Plus™ instrument ON and allow it to warm for 15 minutes.
2. Use a cartridge, with the plunger assembly removed and filled with 0.2 to
0.3 mL of water. Insert the cartridge into the actuator heat block.
3. Place a calibrated thermometer in one of the cartridge reaction chambers.
4. Wait for temperature equilibration to occur (minimum 10 minutes) and check
the thermometer reading.
5. The instrument-displayed temperature and thermometer-measured
temperature should both read within 36.5°C to 37.5°C. The thermometer-
measured temperature should be within ± 0.5°C of the instrument-displayed
temperature.
From the Quality Control Menu:
6. To change the temperature, if needed, or record that the temperature has
been verified, select [Temperature Adjustment].
7. Enter the thermometer reading using the keypad (values must be between
35°C and 39°C).
8. To accept the value, press [Enter]. The time, date, and temperatures of the
thermometer and the display will be logged in the temperature log.
Note: If the instrument is still not in the range specified (see Step 5), adjustments
can be repeated after a minimum of 10 minutes. To repeat adjustments, select
[Repeat Adjustment].
9. If you are unable to calibrate the display to match the thermometer-measured
temperature, contact the Medtronic Service Representative or an authorized
distributor.
