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°C.

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.

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.

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.
