The manual for the B+K Precision Models 5460, 5470, and 5490 digital multimeters covers setup, operation, and troubleshooting, including instructions for measuring various electrical parameters such as voltage, current, resistance, and frequency. It also provides safety precautions, maintenance guidelines, and specifications for each model, with additional features like autoranging, bargraph display, and RS-232 capability for the 5490 and 5470 models.
Manual Overview
The B+K Precision Model 5490 is a bench-type digital multimeter designed for precise measurements, including AC/DC voltage, current, resistance, and more. It features high accuracy with 0.025% DCV and 0.07% Ohms accuracy, and a 100kHz AC response. The multimeter supports autoranging, bargraph, and zoom functions, and can measure capacitance up to 50,000 µF. It also includes features like frequency, duty cycle, pulse width, and dB across 1Ω to 10kΩ. The Model 5470 shares similar features but lacks pulse width, event counting, and VA measurement, while the Model 5460 offers a more economical option with reduced accuracy and fewer features. All models comply with safety standards and include a 50,000 count resolution display. Troubleshooting involves checking for blown fuses indicated by the display, and ensuring proper function selection using the rotary switch. Calibration and adjustments are facilitated by the RS-232 capability in models 5490 and 5470. Safety precautions are critical, especially when dealing with high voltage, and include using isolation transformers and avoiding contact with metal objects during measurements.

Safety & Warnings
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 since it can produce a lethal current under certain conditions. Higher voltages are even more dangerous. Observe the following safety precautions:
– Do not exceed the specified input ratings for DC volts, AC volts, ohms, and current to prevent personal injury or damage to the instrument.
– Never use the multimeter unless the case is closed.
– Remove test leads before performing any service on the multimeter.
– Use only safety type test leads like those supplied with the multimeter.
– Turn off equipment while making test connections in high-voltage circuits and discharge high-voltage capacitors after removing power.
– Do not touch equipment, meter, or test leads while power is applied when making voltage or current measurements in high-voltage equipment.
– Familiarize yourself with the equipment being tested and the location of its high voltage points, but remember that high voltage may appear at unexpected points in defective equipment.
– Use an insulated floor material or floor mat to stand on, and an insulated work surface; ensure such surfaces are not damp or wet.
– Keep one hand in the pocket while handling an instrument probe to avoid contacting a nearby metal object that could provide a good ground return path.
– For equipment with a two-wire ac power cord, including some with polarized power plugs, use an isolation transformer between the ac outlet and the equipment under test to avoid a serious shock hazard.
– 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 (cardio-pulmonary resuscitation) first aid is highly recommended.
