Calibration Test with DSTA-40
The DSTA-40 TEMP CHECK (DSTA-40) is an electronic
thermometer used to verify the recirculating solution operating
temperature of the Fluid Warmer. The DSTA-40 uses thermistor
technology to sense the temperature of the recirculating solution
temperature for the Fluid Warmer. The recirculating solution
temperature is displayed by a liquid crystal display (LCD). The DSTA-
40 is powered from the auxiliary outlet of the Fluid Warmer. No
batteries are required.

Note: The Level 1 DSTA-40 TEMP CHECK is available for purchase
from Smiths Medical.
Proper calibration of recirculating solution temperature
Confirm proper calibration of recirculating solution temperature by
performing the following steps:
1 Unplug the power cord for the base assembly from the auxiliary
outlet on the bottom of the Fluid Warmer.
2 Plug the DSTA-40 TEMP CHECK into the auxiliary outlet.
3 Install the DSTA-40 TEMP CHECK in the heat exchanger
position (#1 Block and #2 Block).
4 Install a test filter in the #3 Block.
5 Turn the Fluid Warmer ON. Allow to warm up until the DSTA-
40 temperature display stabilizes.
6 Compare the DSTA-40 TEMP CHECK temperature display with
the temperature display on the Fluid Warmer's Display Panel.
Using a flat-head screwdriver, open the Fluid Warmer's faceplate at
the left and right corners, and look at the LCD temperature display.
If the DSTA-40 reads 41.7C and the Fluid Warmer's temperature
display is within the range of 41.4 C - 42.0 C, the calibration is OK.
Push the Fluid Warmer's faceplate back into place.
Note: The Fluid Warmer's temperature display must read within
0.3°C of the Level 1
properly calibrated unit.
7 Unplug the DSTA-40 TEMP CHECK and plug the power cord
from the base assembly into the auxiliary outlet.
