Safety & Warnings
Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must sometimes be performed where exposed voltage is present. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. A voltage as low as 35 volts dc or ac (rms.) should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. Higher voltages pose an even greater threat because such voltage can more easily produce a lethal current. Your normal work habits should include all accepted practices to prevent contact with exposed high voltage and to steer current away from your heart in case of accidental contact with high voltage. You will significantly reduce the risk factor if you know and observe the following safety precautions:
– Don’t expose high voltage needlessly. Remove housings and covers only when necessary. Turn off equipment while making test connections in high voltage circuits. Discharge high voltage capacitors after removing power.
– If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. However, remember that high voltage may appear at unexpected points in defective equipment.
– Use an insulated floor material or a large, insulated floor to stand on and an insulated work surface on which to place equipment and make certain such surfaces are not damp or wet.
– Use the time-proven “one hand in the pocket” technique while handling an instrument probe. Be particularly careful to avoid contacting a nearby metal object that could provide a good ground return path.
– When testing ac powered equipment, remember that ac line voltage is usually present on some power input circuits such as the on-off switch, fuses, power transformer, etc., any time the equipment is connected to an ac outlet, even if the equipment is turned off.
– Some equipment with a two-wire ac power cord, including some with polarized power plugs, is the “hot chassis” type. This includes most recent television receivers and audio equipment. A plastic wooden cabinet insulates the chassis to protect the customer. When the cabinet is removed for servicing, a serious shock hazard exists if the chassis is touched. Not only does this present a dangerous shock hazard, but it can also damage test equipment. Always connect an isolation transformer between the ac outlet and the equipment under test. The B&K Precision Model TR-110 or 1604A Isolation Transformer or Model 1653A or 1655A AC Power Supply is suitable for most applications. To be on the safe side, treat all two-wire ac equipment as “hot chassis” unless you are sure it is isolated chassis or an earth ground chassis.
– On test instruments or any equipment with a 3-wire ac power plug, use only a 3-wire outlet. This is a safety feature to keep the housing or other exposed elements at earth ground.
– B&K Precision products are not authorized for use in any application involving direct contact between our product and the human body or for use as a critical component in a life support device or system. Here “direct contact” refers to any connection from or to our equipment via any cabling or switching means. A “critical component” is any component of a life support device or system whose failure to perform can be reasonably expected to cause failure of that device or system or to affect its safety or effectiveness.
– Never work all alone. Someone should be nearby to render aid if necessary. Training in CPR (cardiopulmonary resuscitation) first aid is highly recommended

Basic Usage and Operation Tips
Before powering on the unit, ensure all connections are secure and the load is properly connected. Use the front panel knobs or GPIB commands to set the desired voltage and current limits. Always start with the current limit set low and gradually increase to prevent damage to the device or connected equipment. Monitor the digital display to verify output parameters during operation. Utilize the memory function to save frequently used settings for quick recall.
Troubleshooting and Maintenance
If the power supply fails to output voltage, verify that the unit is properly connected to AC power and that the fuse is intact. Check all cables and load connections for continuity. In case of unexpected shutdowns, inspect for overheating and ensure adequate ventilation around the unit. Regularly clean the exterior with a dry cloth and avoid using solvents. Periodically check the calibration to maintain accuracy, and contact authorized service centers for repairs beyond basic troubleshooting.
