The B & K-Precision Model 2910 R/C PAK manual provides instructions for setting up and operating the resistor/capacitor substitution box, detailing how to select and substitute various resistor and capacitor values for circuit testing. It also includes troubleshooting tips, such as observing the overvoltage warning lamp to prevent damage to low voltage electrolytic capacitors, and provides warranty service instructions for repairs.
Manual Overview
The B&K Precision Model 2910 R/C PAK is a resistor/capacitor substitution box designed for a wide range of resistance and capacitance values. It includes carbon resistors from 10 ohms to 6.8 Megohms and capacitors from .0001 uF to 1000 uF. The device features a pushbutton switch for electrolytic capacitors, ensuring safe discharge to prevent circuit damage. Troubleshooting involves checking the warning lamp for overvoltage before using the 1000 uF capacitor. Calibration requires setting the slide switch to the appropriate range (RX1 for lower resistance and RX1K for higher) and using the rotary selector to choose the desired value. Board-level guidance includes ensuring proper connection of test leads and observing caution when switching settings to avoid damage. For warranty service, units must be securely packed and sent to an authorized service agency with a description of the issue. The warranty covers defects in workmanship and materials for one year but excludes misuse or unauthorized repairs.
Quick Issues Covered
- Diagnose overvoltage with warning lamp before capacitor substitution.
- Error codes for incorrect rotary selector switch settings.
- Schematics assist in tracing capacitor and resistor connections.

Operation
The B & K-Precision Model 2910 R/C PAK resistor/capacitor substitution box allows for the substitution of resistors and capacitors in circuits. For carbon resistors, the device can substitute 24 resistance values, with specific wattage for different ranges. To use, set the slide switch to the appropriate position (RX1 or RX1K), dial the required value on the rotary selector switch, and connect the test leads to the circuit. For disc and tubular capacitors, set the slide switch to the CAP position, dial the required value, and connect the leads. After testing, discharge the capacitor by shorting the leads. For electrolytic capacitors, ensure the ELECTROLYTICS switch is in the DISH position, set the slide switch to CAP, and use the rotary selector for the desired value. The warning light should be observed when using the 1000 uF capacitor to prevent exceeding voltage limits.

Safety & Warnings
The manual includes the following safety warnings and precautions:
1. Electrolytic capacitors are not connected to the circuit for substitution until the ELECTROLYTICS pushbutton switch is pushed. When pressed again, the switch releases to the DISH position and automatically discharges the capacitor to prevent it from discharging into the next circuit.
2. The low voltage electrolytic capacitor is protected by an overvoltage warning lamp that lights up before the ELECTROLYTICS switch is pushed, which helps prevent damage from excessive voltage.
3. When using the 1000 uF electrolytic capacitor, observe the warning light. If it is lit, the 80-volt rating of the capacitor will be exceeded if the ELECTROLYTICS switch is pushed.
4. Do not change the setting of the rotary selector switch when the ELECTROLYTICS switch is in the SUB position. This could cause severe damage to the rotary switch or destruction of the 1000 uF, 80-volt capacitor from overvoltage.
