The manual for the B&K Precision Model 1682A DC Power Supply provides detailed instructions for setting up the device, including line voltage conversion and fuse replacement, as well as guidance on operating the power supply and troubleshooting common issues. It also includes information on obtaining repair services and technical support from B&K Precision, along with safety warnings to prevent electrical shock.
Manual Overview
The B&K Precision Model 1682A DC Power Supply manual provides essential guidance for troubleshooting, calibration, and maintenance. For troubleshooting, if the power supply fails to operate and the power ON LED does not light, check the fuse located on the rear panel. A blown fuse typically indicates a problem within the unit, and it should be replaced with a fuse of the correct rating after identifying and correcting the underlying issue. The manual specifies fuse values of 5A for 115 VAC and 2.5A for 230 VAC. For line voltage conversion, the power transformer can be adjusted for 120 or 220 VAC by changing the position of the Line Voltage Select switch on the chassis bottom. This conversion requires a corresponding change in fuse value. The manual advises that repairs and calibrations should be performed by qualified personnel or through B&K Precision’s authorized service network, as specialized skills and equipment are necessary. The manual emphasizes safety, warning against electrical shock risks, especially when dealing with high voltage equipment.
Quick Issues Covered
- Diagnose power-up failures via fuse and LED indicator checks.
- Perform line voltage conversion by adjusting chassis switch.
- Trace circuits using detailed schematics for troubleshooting.

Safety & Warnings
The manual includes the following safety warnings and precautions:
1. Servicing should only be performed by qualified personnel to avoid electrical shock. Do not perform any servicing other than what is contained in the operating instructions unless qualified to do so.
2. If the fuse blows, the power ON LED indicator will not light, and the power supply will not operate. Determine and correct the cause of the blown fuse before replacing it with a fuse of the correct rating.
3. When converting line voltage, ensure the power cord is unplugged and install the correct fuse value as listed.
4. An electrical shock causing 10 milliamps of current to pass through the heart can stop most human heartbeats. Voltage as low as 35 volts DC or AC rms should be considered dangerous and hazardous as it can produce a lethal current under certain conditions.
5. There is little danger of electrical shock from the DC output of this power supply. However, if the equipment under test uses high voltage in any of its circuits, a shock hazard may be present.

Basic Usage and Operation Tips
Before use, ensure the multimeter is properly calibrated and the test leads are in good condition. Select the appropriate measurement mode based on the parameter you want to test. For voltage measurements, connect the probes in parallel with the circuit component. For current measurements, connect the probes in series. Always start with the highest range to prevent damage and then adjust downwards for more precise readings. Use the data hold function to freeze the displayed measurement for easier recording.
Troubleshooting and Maintenance
If the device does not power on, check the battery and replace it if necessary. Clean the test leads and connectors regularly to ensure accurate readings. Avoid exposing the multimeter to extreme temperatures, moisture, or dust. If readings appear inconsistent, verify the calibration or consult the manual for detailed troubleshooting steps. Store the device in a protective case when not in use to prolong its lifespan.
Safety Reminder
Always observe proper safety precautions when using the Bk-precision-1682a. Do not exceed the maximum input limits to avoid electric shock or damage to the device. Use insulated test leads and avoid contact with live circuits. Disconnect power before measuring resistance or continuity. Follow all local electrical safety regulations and guidelines to ensure safe operation.
