INTRODUCTION B&K Precision’s 830C and 890C 11,000-count hand- held capacitance meters measure capacitance and include a capacitance sorting function. Simple to operate, instruments make quick measurements and simplify the capacitance sorting process. Capacitance is measured by using a small DC voltage signal that slightly charges the connected capacitor for a short time.
Page 14
A single 9V battery or the included DC 12V power adaptor (included with model 830C only) can be used to power the meter. This gives user flexibility for portable or bench-top use.

Static Recording This mode is used for recording maximum, minimum, and average capacitance values. It captures only stable values and updates to memory. Values that result in displaying “OL” or that are below 10 counts are not recorded. This mode is useful for determining the range of values a component falls into.
Page 56
Recording Mode Maximum Mode Minimum Mode Average Mode Recording Mode This is the default mode when first enabling static recording. In this mode, the “MAX AVG MIN” indicator will be displayed. At this point, the meter will start recording measured values applied to the input sockets or terminals.
Page 57
Minimum Mode In this mode, the “MIN” indicator will be displayed. This indicates that the value in the primary display represents the recorded minimum value. Average Mode In this mode, the “AVG” indicator will be displayed. This indicates that the value in the primary display represents the recorded average value.

Relative Mode Relative mode is used when the user wants to “zero” the meter based on a reference value or wants to obtain a reading that is relative to a reference value. For example, if test leads are used in the measurement, the user may want to set a reference with the test leads inserted into the input terminals so that any measurements taken will not take into...

have test leads or wires connected to the meter in the fashion that they desire. Then, press the button once to “zero” out the meter as reference. This way, any measurements taken would not be affected by the test leads or setup. Note: Relative mode can be set in both auto and manual range, but cannot be set when “OL”, or overload is displayed on the meter.
Tolerance The tolerance mode feature is specifically used for component sorting purposes. Users who need to test and sort through a large number of components will find this function quite helpful. Tolerance Range The tolerance function is configured primarily by percentage range, meaning a percentage is used to define whether a measured value is within tolerance or out of tolerance.

2. Once the desired measured reading is displayed, press the button once to store the reading as the “standard” value or test reference value. At this point, the “TOL” will be displayed on the screen, indicating that the tolerance mode is activated. 3.
Page 65
Note: Under the following instances, the tolerance mode cannot be set: 1. After setting recording mode 2. After setting HI/LO limit for compare mode 3. The display shows “OL” for overload. Disable Tolerance Mode To disable or exit out of tolerance mode, simply press and hold down the button for two seconds.

REMOTE COMMUNICATION The meter has the capability to communicate with a PC over the mini USB interface. Upon installation of a USB driver, the PC can control the instrument over virtual COM. The mini USB communication interface of the meter is fully duplex and has a 64-byte input and output buffer, making it reliable and efficient for data transmission.
PC, thus serial port settings must be configured properly for remote communication to be successful. Below are the default settings used by the 830C and 890C meters. They can be changed within the setup menu. See SETUP OPTIONS section for details.
Command Protocols Overview of Command Type and Format All commands are entered in either the upper case or the lower case. There are two types of the meter programming commands: IEEE 488 common commands and Standard Commands for Programmable Instruments (SCPI). Some commands are device-specific to the meter.

MEASUREMENT TIPS To avoid possible damage to the meter or the equipment under test, disconnect circuit power and discharge the capacitor before measuring capacitance. Capacitance is the ability of a component to store an electrical charge. The unit of capacitance is the farad (F).

to subtract the residual capacitance of the meter and leads or tweezer. 3. Insert the leads of capacitor into “+” and “-” input sockets, respectively. If you are using alligator clip leads or SMD tweezer, connect the “+” and “-“ ends to the capacitor respectively.
SUPPLEMENTAL INFORMATION Guard Terminal One of the input sockets and terminals is labeled as “GUARD”. This terminal does not have to be used in all instances for the meter to make measurements. But in some instances, it is very useful. The guard terminal is used to minimize noise and to help minimize parasitic components of the capacitor to be measured, thus allowing for more accurate results.
