To test batteries, press switch to RIGHT (momentary) position; LED should light. 2. OFF position is with switch in center. 3. To turn unit ON, press to LEFT. Use LA704B line adaptor to power unit from line voltage without batteries installed or to charge Ni-Cad batteries. Test for proper operation
- Use a digital multimeter to verify that the proper voltage and current are available at the transducer connector.
- Substitute an oscillator for the transducer.
- Follow the connection to the power unit as shown at right.
- The unit should have unity again. CAUTION: DO NOT ATTEMPT TO RECHARGE ALKALINES WITH THE LA704B. Alkaline batteries may EXPLODE or leak corrosive fluids. 98450 Rev.C.1 09/18 To transducer connector of channel under test.
