The BK Precision Sweep Function Generator manual provides detailed instructions for setting up and operating models 4001A and 4003A, including generating various waveforms and using the frequency counter feature. It also offers guidance on troubleshooting, maintenance, and safety precautions to ensure proper and safe use of the equipment.
Manual Overview
The BK Precision 4001A and 4003A Sweep Function Generators are designed to produce various waveforms including sinusoidal, triangular, ramp, square, and pulse, with frequency settings ranging from 0.5 Hz to 4 MHz. The 4003A model also features a 20 MHz digital counter. For troubleshooting, the manual emphasizes understanding the frequency characteristics and output settings. The frequency can be adjusted using a range selector switch and a frequency control knob, with a multiplication factor from 0.04 to 4.0. The output amplitude ranges from 0.2 V to 20 Vpp without load and 0.1 V to 10 Vpp with a 50-ohm load. Calibration involves ensuring frequency stability, which should not deviate more than 0.1% within 15 minutes of operation or 0.2% over 24 hours. The manual provides guidance on using the sweep generator for linear or log sweeps and adjusting sweep rates and widths. The 4003A model includes an auto-ranging, 5-digit frequency counter for both internal and external functions.

Operation
The manual provides information on the operation and basic usage steps of the BK Precision 4001A and 4003A Sweep Function Generators. These models are capable of generating sinusoidal, triangular, ramp, square, and pulse waveforms, selectable through a rotary switch. The frequency can be set from 0.5 Hz to 4 MHz using a range selector switch and a frequency control knob, with a multiplication factor of 0.04 to 4.0 of the selected frequency range. The signal amplitude is adjustable from 0.2 V to 20 Vpp with no load and 0.1 V to 10 Vpp with a 50 ohm load termination. The MAIN output includes a SYNC output signal (TTL level) option. The sweep generator offers linear or log sweep with variable sweep rate and adjustable sweep width (model 4003A only). An auto-ranging, 5-digit frequency counter is available with a range from 0.2 Hz to 20 MHz and a resolution of 0.01 Hz, used for both external and internal functions (model 4003A only). Additionally, an external voltage signal can control the frequency, and with an AC input signal, FM output can be generated.

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.
1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Some equipment with a two-wire AC power cord, including some with polarized power plugs, is the “hot chassis” type. 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 damage to test equipment. Always connect an isolation transformer between the AC outlet and the equipment under test. The B&K Precision Model TR-110 or 1604 Isolation Transformer or Model 1653 or 1655 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.
7. 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.
8. 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.
9. Never work all alone. Someone should be nearby to render aid if necessary. Training in CPR (cardio-pulmonary resuscitation) first aid is highly recommended.

Basic Usage and Operation Tips
Before using the multimeter, ensure the device is set to the correct measurement mode and range for your application. Connect the test leads securely to the appropriate input jacks and the circuit under test. For DC measurements, observe proper polarity to avoid inaccurate readings. Use the data hold function to freeze displayed values when needed. Always start with the highest range if unsure of the expected measurement to prevent damage.
Troubleshooting and Maintenance
If the multimeter displays erratic readings or fails to power on, check the battery and replace it if necessary. Inspect test leads for any visible damage or wear and replace them if compromised. Clean the device regularly with a dry cloth and avoid exposure to moisture or extreme temperatures. If the device shows “OL” or overload, reduce the measurement range or verify the test circuit to prevent damage.
Safety Reminder
Always observe proper safety precautions when working with electrical equipment. Do not exceed the maximum input limits specified in the manual. Avoid measuring live circuits if you are unsure of the procedure or if the device is damaged. Use insulated test leads and wear appropriate personal protective equipment to minimize the risk of electric shock or injury.
