The B & K Precision Model 830A Autoranging Capacitance Meter manual provides instructions for setting up and operating the device, including details on using the autoranging feature, the hold function for batch testing, and the procedure for measuring capacitance with the device. It also covers troubleshooting tips such as ensuring the meter is zeroed before measurements, handling overrange conditions, and replacing batteries when the low battery indicator appears.
Manual Overview
The B&K Precision Model 830A Autoranging Capacitance Meter is designed for direct capacitance measurement with a 3.5-digit LCD display. It features automatic range selection across ten scales from 199.9 picofarads to 199.9 millifarads, ensuring high resolution. The meter includes a hold function to lock the range during batch testing. For troubleshooting, ensure the meter is zeroed before use by pressing the AUTO ZERO switch, and avoid applying voltage to the test jacks to prevent internal damage. Error diagnostics include an “01” display during autoranging or if a shorted capacitor causes overrange. An open capacitor will read a few picofarads. Calibration involves ensuring the display reads 00.0 ±1 digit when zeroed. For board-level guidance, the meter can measure capacitance directly from the test socket or via clip leads for capacitors without leads. The device operates on a 9V battery, with an optional AC adapter, and features a low battery indicator. Regular battery checks and replacements are advised to maintain accuracy.
Quick Issues Covered
- Diagnose overrange errors with '01' display on LCD.
- Calibrate using AUTO ZERO for accurate measurements.
- Resolve power-up failures with battery replacement or AC adapter.

Operation
The B & K Precision Model 830A Autoranging Capacitance Meter is designed to measure capacitance directly on a 3-½ digit crystal display. It features an autoranging function that automatically selects the range with the highest resolution, covering ten full scale ranges from 199.9 picofarads to 199.9 millifarads. The meter includes a hold feature that prevents the range from resetting when a capacitor is removed, facilitating faster batch testing of large value capacitors. It is suitable for use in electronic engineering labs, production, service shops, and schools, and can be used for checking tolerance, sorting values, selecting precision values, measuring unmarked capacitors, selecting matched sets, and measuring cable or switch capacitance. The meter is portable due to its battery operation, light weight, and small size.
To operate the meter, follow these steps:
1. Set the POWER switch to the ON position.
2. Zero the meter by pressing the AUTO ZERO switch. The display should read 00.0 ± 1 digit. If using test leads, connect them to the “+” and “-“ jacks before zeroing the meter.
3. For capacitors with leads, insert the leads directly into the slotted capacitor test socket. For capacitors without leads, plug test leads into the “+” and “-“ jacks and clip the test leads to the capacitor terminals.
4. Read the capacitance value directly from the LCD display and its accompanying unit indicator LED. The meter starts on the lowest range (200 pF full scale) and automatically ranges upward to the appropriate range for maximum resolution. The display reads “01” until the proper range is reached.
5. For faster measurement of a group of similar value capacitors, especially large values over 200 uF, press the HOLD switch before removing the first capacitor. This locks the meter on that range and reading, eliminating the need for automatic upranging for subsequent measurements. Press the HOLD switch again after measuring the next similar capacitor.
Ensure capacitors are fully discharged before measurement, and observe polarity when connecting polarized capacitors. The meter applies a maximum of 4 volts to the capacitor being measured.
Troubleshooting & Error Codes
Refer to the PDF for details.
Safety & Warnings
1. Never apply voltage to the test jacks; serious internal damage may result.
2. Fully discharge any capacitors before measurement.
3. Observe polarity when connecting polarized capacitors.
4. Remove discharged disposable batteries immediately to prevent leakage.
