INTRODUCTION
B&K Precision ’s 830C and 890C 11,000-count handheld capacitance meters measure capacitance and
include a capacitance sorting function. Simple to
operate, the instruments can make quick
measurements and simplify the capacitance sorting
process.
Capacitance is measured by using a sm all D C vo ltag e
signal that slightly charges the c onn ec ted cap ac itor f or
a s hort time. Unlike other handheld instrum ents such
as LCR meters, it does not use an AC signal with a
specific test frequency to make measurements.
Front panel push buttons maximize the convenience
of function and feat ure selection. T he meters support
the following modes: Tolerance sorting mode,
relative mode, data hold, manual and auto range
mode, min/max/avg recording, and high/low limit
setting.
Test data can be trans ferred to a PC throug h a Mini
USB connection, which is useful for data logging
applications.
A tilt stand provides position flexibility for viewing and
operating the meter. The over-molding rubber case
11
protects the meter for better durability. Additionally,
the top rubber visor molding above the screen is
designed to prevent scratches on the display when
the meter is positioned upside down.
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 us e.

WARNING: Before connecting an external
power adapter, please check the battery
compartment in the rear side of the uni t. If
a battery is installed, be sure that the
polarity matches the (+) and (-) labels as
indicated inside the battery compartment.
If it is not installed correctly, please
remove the battery and install i t with
correct matching polarity as indicated in
the compartment. See “Installing Battery
section for details. DO NOT, at any time,
connect an external power adapter when a
battery is installed incorrectly. Doing so
will damage the instrument and void its
warranty.
Front Panel Buttons
All front panel buttons have specific colored labels on
them. They are all marked in white, blue, or yellow
color. Each color has a specific representation, as
described below:
”
White – With the exception of the
button, all white colored labels
represent the primary function of that
16
button; meaning that function will be
set or configured upon pressing it. To
escape out of the functions, hold and
press the corresponding button for
two seconds.
Blue – Some of the buttons have a blue label
underneath a white label. This means
the function indicated by the blue
label will be set if that button is
pressed and held for 2 seconds.
Yellow – There are total of 6 buttons with
yellow labels. They are
. These functions are
exclusively for use when entering the
SET menu for configuring setup menu
items as well as compare function.
See “Setup Menu” and “Compare
Mode” sections respectively for
details.

POWERING INSTRUMENT
Before operating the instrument, make sure to
connect it to a power source, which could be either a
battery or an external AC adapter.
Installing Battery
The 830C and 890C capacitance meters can be
powered by a battery, thus making it portable.
The meters use a standard 9V size battery (or
NEDA 1604, JIS006P, IEC6F22 carbon-zinc or
alkaline battery).
To install the battery:
1. Place the meter upside down. Open up the
back-flip stand, and locate the screw that
tightens the battery compartment cover as
indicated in Figure 4. Use a screwdriver to
unscrew and remove the cover.
22
Figure 4 - Back Cover
2. Insert 9V battery into compartment. Note the
positive (+) and negative (-) terminals as
indicated inside the battery compartment (See
Figure 5). Be sure to insert the batter y with
matching polarity.
23
Figure 5 - Battery Compartment
3. Place the battery compartment cover piece by
sliding it into the top slid first. Place screw at
the bottom of the cover piece and tighten
down with a screw driver.
4. Push and hold down the button for 2
seconds to turn on the instrument.
Connecting External Power Source
The 830C and 890C can also be powered using an
external AC adapter. The model 830C comes with
this adapter includ ed in the pac kage, while it is
optional for model 890C. There are two types
available. One with 110 V AC line voltage input, and
one with 220 V AC li ne volt age input. Be sure to use
24
one that has the correct AC line voltage input for use
in your country.
For external power, use AC adapter rated for
output 12VDC, 150mA, with a standard 4mm
connector only.
WARNING: Use of incorrect adapters may damage
the instrument. Please use B&K Precision’s adapter
only. Be sure to use one with the correct AC line input
voltage.
To connect the adapter, do the following:
1. If a battery is installed, please check the
battery compartment again that the polarity of
the battery matches the polarity as indicated
by the labels inside the compartment. If it is
not, please remove and insert the battery with
matching polarity. If a battery is not installed,
continue to the next step.
WARNING: DO NOT, at any time, connect
an external power adapter when a battery
is installed incorrectly (reverse polarity or
non-matching polarity to indicator of
battery compartment). Doing so will
damage the instrument and void its
warranty.
25
12VDC Input
AC Adapter
Figure 6 - Connecting AC Adapter to Meter
2. Connect the AC adapter connector into the
right side panel of the instrument. See Figure
6 below.
3. Now, connect the AC Adapter socket into an
electrical outlet.
4. Push and hold down the button for 2
seconds to turn on the instrument.
Note: The meter can be operated with a battery
installed while an AC adapter is plugged in at the
same time (As long as the battery is inserted properly
with correct polarity). In this event, the meter will
automatically switch to consume power from the AC
adapter instead of the battery to preserve battery life.
26
Low Bat tery Indication
The capacitance meter has a low battery indicator to
notify the user when to replace the battery. When the
display starts flashing the indicator, the battery
voltage is below normal working voltage. In this case,
accuracy of the meter will also decrease. It is
recommended that the battery be replaced as soon as
possible before continuing operation. See “Installing
Battery” for instructions.
Backlit Display
The capacitance meter has a backlit display that
allows you to see the LCD display in dark conditions.
To turn on the back light, press and hold the
button for 2 seconds. Back light will turn on and
brighten the LCD display.
To turn off the back light at any time, press and hold
the button for 2 seconds again. Back light will
turn off and return to normal display.
27
When Using Battery Power
When the meter is powered using 9V battery, the back
light display will turn on upon holding the
button for 2 seconds. It will stay at maximum
brightness for 15 seconds if backlight settings are set
to default value.
When Using External Power
When the meter is powered using an external AC
adapter, the back light display will turn on upon
pressing and holding the button for 2 seconds.
It will stay at maximum brightness continuously until
the user presses and holds the button for 2
seconds again.
Note: If a battery is installed while using an AC
adapter simultaneously, un plu ggi ng the AC ada pter
will automatically start the back light timer configured
under “SETUP OPTIONS” and back light will turn off
once the time is up.
