Operation
The manual provides operating instructions for the Model 1735A DC Power Supply, which offers 0-30 volts DC output and 0-3 amps current output. It features coarse and fine controls for both voltage and current adjustments. The power supply can operate in either constant voltage or constant current modes, with smooth and automatic crossover between the two. LED indicators show whether the unit is in constant voltage (CV) or constant current (CC) mode. The unit includes reverse polarity protection and overload protection with fully adjustable current limiting. The output is isolated from the chassis and earth ground, allowing for flexible connections. Two power supplies can be connected in series or parallel for increased voltage or current output.

Safety & Warnings
Normal use of test equipment can expose users to electrical shock, especially when testing where high voltage is present. An electrical shock with 10 milliamps of current through the heart can be lethal. Voltage as low as 35 volts can be dangerous and hazardous. Users should adopt safety practices to avoid contact with high voltage and steer current away from the heart. Specific precautions include:
1. The DC output of the power supply poses little shock danger, but certain test conditions can create high voltage shock hazards:
a. A serious shock hazard exists with “hot chassis” type equipment unless it is unplugged or an isolation transformer is used.
b. If the equipment under test is powered and uses high voltage, the power supply outputs may float to a high potential. Do not float the output to more than 100 volts peak with respect to chassis or earth ground.
c. Discharge high-voltage capacitors before making connections or tests if the equipment uses high voltage in normal operation.
2. Use a polarized 3-wire AC outlet to ensure the power supply chassis, case, and ground terminal are connected to a good earth ground, reducing shock danger.
3. Avoid unnecessary exposure to high voltage. Remove housings and covers only when necessary, turn off equipment while making test connections in high-voltage circuits, and discharge high-voltage capacitors after removing power.

Basic Usage and Operation Tips
Before using the Bk-precision-1735a, ensure the device is properly calibrated and the battery is sufficiently charged. Select the appropriate measurement mode using the rotary switch. Connect the test leads securely to the device and the circuit under test. For voltage measurements, connect the leads in parallel; for current measurements, connect them in series. Use the data hold function to freeze readings for easier analysis. Always start with the highest range setting to prevent damage to the meter and then adjust downward for more precise readings.
Troubleshooting and Maintenance
If the display shows erratic readings or no readings at all, check the battery level and replace if necessary. Inspect the test leads for any damage or wear and replace them if faulty. Clean the device regularly with a soft, dry cloth and avoid exposure to moisture or extreme temperatures. If the meter fails to operate correctly after these checks, consult the manual for detailed troubleshooting steps or contact authorized service centers.
Safety Reminder
Always observe proper safety precautions when using the Bk-precision-1735a. Never exceed the maximum input limits specified in the manual. Avoid measuring voltages or currents in circuits that exceed the device’s rated capacity. Disconnect test leads from the circuit before changing measurement modes. Use insulated gloves and safety glasses when working with high voltages to prevent electric shock or injury.
