8. If you are unable to calibrate the display to match the temperature on the
Temperature Verification Cartridge, contact the Medtronic Service
Representative or an authorized distributor.

Verification with Thermometer

1. Turn the ACT Plus
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 temperature is still not within the specified range (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.

Fuse Replacement

Two fuses are located in the Power Inlet Module on the ACT Plus
rear panel. To replace or examine the fuses:
1. Disconnect the power cord.
2. Open the cover of the fuse holders using a small flathead screwdriver.
3. Slide the fuse holders out and, if necessary, replace the fuses with T2A 250-V
fuses.
4. Insert the fuse holders back into the Power Inlet Module.
5. Close the cover.
6. Power ON the instrument to determine if replacing the fuse(s) corrected the
power failure.
