MEGASONIC ENERGY METER OPERATION MANUAL

© ppb, Inc.

SAFETY PRECAUTIONS ELECTRICAL The cavitation energy meter contains a 7.2 volts rechargeable Nickel-Cadmium battery. Always use extreme caution when recharging. Battery pack is shipped charged. Charge will occur in 12 - 14 hours at 150 mA. The pack is rated at 1,700 mA-hr. Charging the battery at faster rates without special chargers cancause overcharging resulting in the violent venting of chemicals and the release of toxic materials from the battery pack causing personal injury and/or property damage. Special precautions should be taken not to short circuit the positive male prong to the case. INSTRUMENT CASE The electronic case is not waterproof. It should not be immersed in water. If water enters the case it should be sentback to ppb for maintenance. Do not attempt to open and dry because it will probably have to be replaced. There are no user serviceable components inside the case. Tamper proof screws are used to secure the cover to the case. Send the complete instrument to an authorized ppb service center for maintenance or repair. CONNECTORS The probe should be connected on the 3-pin male receptacle located ontop of the meter above the LCD display. The RS-232 cable should be connected on the 4-pin male receptacle located on the left side of the meter next to the battery charger receptacle. Do not force the plugs into the receptacles and caution should be taken not to try to force these plugs into the wrong male receptacles. To disconnect the probe or the RS-232 cable from the meter it is necessary todepress the latch located on the side of each plug before and during removal.

Notes: 1. Keep battery charging while not in use. 2. The sensitivity and calibration knobs are located on the same side as the probe receptacle. 3. After turning the meter ON, wait 3 to 5 seconds before use to allow built-up energy to discharge. 4. Please review the Calibration (appendix C & D) and Operational(appendix E) procedures prior to first use.
