Instructions for installation

1. Install the device on a solid surface.
2. Make sure the power is off before plugging in the device.
3. Keep the device away from the environment with direct sunlight, high temperature, high humidity or severe change in temperature.
4. Make sure the AC power and its grounding plug are properly connected.
5. Do not use power extension cords.
6. Use pure water or distilled water only for the water bath to avoid contamination or water heater breakdown.
7. Pay attention to the water level to avoid overspill.
8. The water bath is to remain 90% full at all times to reach water temperature stability.

Operation procedures

1. Check the accuracy

Step 1: Check water level of the bath.
Step 2: Turn on the device.
Step 3: Select a testing temperature on the control panel (default at 37°C).
Step 4: Wait for the water to reach the desired temperature.
Step 5: Choose the blackbody cavity corresponding to the thermometer types.
Step 6: Set the thermometer into the calibration mode.
Step 7: Insert the probe/tip into the cavity.
Step 8: Start the measurement.
Step 9: Thermometer will beep when the measurement is completed.
Step 10: Compare the reading given by the thermometer to the calibration temperature. The acceptable allowance is within ± 0.2^ .

2. Drain the water bath

Step 1: Make sure the device is off.
Step 2: Remove the tube from the upper end.
Step 3: Empty the water bath by lowering the upper end of the tube.
Step 4: Plug the tube back in after the draining is completed.

Cautions and maintenance

1. Make sure the device, AC power and its grounding plug, is plugged in properly.
2. Change water periodically, once a month is suggested.
3. Use pure water or distilled water only for the water bath. Other water sources might increase the chance of calcium carbonate formation on the outside of the water heater.
4. Make sure there is enough water in the water bath every time before using the device. Please constantly pay attention to the water level and hygiene when/if the device runs for over 6 hours or the water temperature exceeds 40^ C.
5. Keep the device away from physical impact.
6. Unplug the device and empty the water bath if the device is going to be inactive for a long time.
7. Unplug the device before moving it or draining the water bath.
8. Clean the water bath with a 3M scrub sponge if any signs of iron oxidization appear.
9. Pay attention to the water temperature to avoid scald.
