After repeating the 0.0 to 2.0 Amp test on the warm PS-610 battery, connect the UB685 battery to a power supply using a suitable ammeter and rheostat set to 50 (. Raise the power supply voltage level and simultaneously reduce the rheostat resistance to 0 ohms to obtain an initial charging current of 0.80 A. Keep the supply voltage fixed at this ...

Pearson Molecular Biology Lab Bench.)Gel electrophoresis is a procedure that separates molecules on the basis of their rate of movementthrough a gel under the influence of an electrical field. The direction of movement is affected by the charge of the molecules, and the rate of movement is affected by their size.

2. Wind about 25 turns of the wire round the soft-iron core, leaving about 2 cm of core showing at the bottom. Mount the electromagnet in a lab stand, clamp & boss so that the bottom end is about 20 cm above the bench top. 3. SWITCH OFF THE POWER SUPPLY. 4. Select 4 volts DC on the power supply unit and connect up the following circuit: 5.

Lab 4. Using Test Equipment. 1 Objective . This lab will familiarize you with more hardware debugging instruments. Each station in 204B has a triple-output bench power supply, a digital multimeter, a pulse generator, and a 100 MHz mixed signal oscilloscope. You will use each of these in this lab. Test equipment can be complex.

A lab bench should always be left in a secure mode. This means that the power to each piece of test equipment should be turned off, the bench itself should be turned off, all AC and DC power and signal sources should be turned down to zero, and all other equipment and components properly stowed with lab stools pushed under the bench.
