TUNING

Tune the power supply in accordance with the following procedures each time a new

converter or probe is used.

1. Ensure that the probe is not immersed in the liquid and that it does not come

in contact with anything.

2. Set OUTPUT CONTROL TO “100”.

3. Set TIMER ON / OFF SWITCH to OFF.

4. Set PULSER to OFF.

5. Set POWER SWITCH to ON, and rotate the TUNE CONTROL clockwise or

counterclockwise until minimum (not maximum) reading (usually less than

30) is obtained on the POWER MONITOR. If minimum reading cannot be

obtained, make certain that the probe is tight. A loose probe will usually

generate a loud piercing sound.

6. Set OUTPUT CONTROL to “60”.

7. Set POWER SWITCH to OFF.

8. If a footswitch is used, plug into the FOOTSWITCH CONNECTOR. Make

sure that the plug is inserted forcefully all the way in.

CAUTION

The power supply should be tuned after the probe has reached operating temperature. When working with

low or high temperature liquids, immerse the probe in the liquid for a few minutes, withdraw the probe

out of the liquid, and then, tune the power supply.

Ensure that the optional micro cup horn does not contain any liquid when tuning the power supply.
