The Bk precision manual provides instructions for setting up and operating the analog multimeter, including details on battery replacement and testing procedures for different voltage ranges. It also offers troubleshooting tips, such as checking and replacing fuses and ensuring test leads are in good condition, to help users maintain the device's functionality.
Manual Overview
The BK Precision Model 114A analog multimeter manual provides detailed instructions for troubleshooting, diagnostics, calibration, and maintenance. For troubleshooting, the manual emphasizes checking battery conditions and replacing them when necessary, especially when the pointer indicates low battery levels. Error diagnostics involve checking the protective fuse, which can be replaced by removing the rear cover secured by a Phillips screw. Calibration and adjustments are guided by testing the batteries using specific function/range settings to ensure accurate readings. The manual advises on board-level guidance by recommending the use of an isolation transformer when servicing equipment with a “hot chassis” to prevent electrical shock. Safety precautions include using insulated materials and avoiding exposure to high voltages. Regular inspection of test leads for damage and ensuring clean contact points is advised to maintain accuracy. The manual also includes warranty information, specifying coverage and exclusions, and provides contact details for service and repairs.

Safety & Warnings
To avoid personal harm and/or damage to the equipment, remove test leads before changing batteries, or fuse, or servicing the meter. When using a probe, only touch the insulated portion and never touch the exposed tip portion. An electrical shock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. 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 currents are even more dangerous. When testing ac powered equipment, remember that ac line voltage is usually present on some power input circuits such as on-off switches, fuses, power transformers, etc., any time the equipment is connected to an ac outlet. This is true even if the equipment is turned off. Never apply input voltages greater than those listed in the “SPECIFICATIONS” section. Personal injury or damage to the instrument may occur. This meter is not recommended for high voltage industrial use; for example, not for measurements of 440 V AC or 600 V AC industrial power mains. The unit is intended for use with low energy circuits to 750 V AC or 1000 V DC high energy circuits to 250 V DC or AC. Accidental misuse by connection across a high voltage, high energy power source when the meter is set up for mA measurement may be very hazardous. Use an insulated floor material or a large, insulated floor mat to stand on, and an insulated work surface on which to place equipment; make certain such surfaces are not damp or wet. Some equipment with a two-wire ac power cord, including some with a polarized power plug, is the “hot chassis” type. This includes most recent television receivers and audio equipment. A plastic or 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. To make measurements in “hot chassis” equipment, always connect an isolation transformer between the ac outlet and the equipment under test.
