The Bk precision manual provides detailed instructions for setting up, operating, and troubleshooting the device, including procedures for battery and fuse replacement, as well as safety precautions to prevent electrical shock. It covers the features of the device such as its multiple voltage, current, and resistance ranges, and includes guidance on using test leads and performing various measurements safely.
Manual Overview
The Bk Precision manual provides essential guidance for maintaining and troubleshooting the device, focusing on battery and fuse replacement, error diagnostics, and safety precautions. For battery replacement, a low battery is indicated by a symbol on the display, and the procedure involves removing screws to access the battery compartment and replacing the battery with a 9-volt alkaline type. Fuse replacement is necessary if current measurements are not possible, with specific instructions for checking and replacing the fuses for different jacks. The manual emphasizes using only the specified fuses to maintain safety and functionality. Safety precautions are critical, including removing test leads before servicing, using safety-type test leads, and being aware of high voltage risks. Calibration and adjustments are not detailed, but the manual outlines the device’s features, including multiple measurement ranges and functions, such as voltage, current, resistance, capacitance, and frequency measurements. The device includes overload protection and an audible warning system to prevent incorrect usage.

Safety & Warnings
Remove test leads before replacing batteries or fuses and before performing any servicing on the instrument. Use only the safety type test leads supplied with the instrument. Turn off equipment while making test connections in high voltage circuits. Discharge high voltage capacitors after removing power. For voltage or current measurements in high voltage equipment, do not touch equipment, meter, or test leads while power is applied. Never apply an external signal to the Cx or hFE input jacks. If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. Use an insulated floor material or floor mat to stand on, and an insulated workbench surface; make certain such surfaces are not damp or wet. Keep “one hand in the pocket” while handling an instrument probe. When using a probe, touch only the insulated portion. Never touch the exposed tip portion. When the cabinet is removed for servicing, a serious shock hazard exists if the chassis is touched. Always connect an isolation transformer between the ac outlet and the equipment under test. When testing ac powered equipment, remember that ac line voltage is usually present on some power input circuits any time the equipment is connected to an ac outlet, even if the equipment is turned off. Never work alone. Someone should be nearby to render aid if necessary. Training in CPR (cardiopulmonary resuscitation) first aid is highly recommended.
