
MEAS RATE Selects the measuring rate. At frequencies of 1 kHz or greater, slow
(2 measurements per second), medium (10 measurements per second, and fast
measurements (20 measurements per seconds) may be selected.

DISPLAY

Average The average of 2 to 20 measurement readings will be displayed.
The number of measurements in the average is selected from the keypad.

HOLD This key holds the meter in its current measurement range. Pressing
the hold key a second time returns the meter to the Auto-Range mode. A
specific range may also be entered from the numeric keys on the keypad.

EQU This key toggles the equivalent circuit for the component under test
between a series or parallel circuit.

DISP The DISP key cycles through the display parameters that may be
selected. The display parameters that may be selected are:

VALUE The measured value of the device under test is displayed.

DEV The deviation from a value previously entered is displayed.

% DEV The percent deviation from a previously entered value is
displayed.

ENTRY Used for entering parameter values.

BINS Selects the bin number when Binning is enabled.
Note: Certain displays are not available unless data has been entered. For example,
DEV and % DEV are not available unless a nominal value has already been entered.
Also, BINS is not available unless binning data has previously been entered.


Backspace key used for correcting mistakes when entering
numeric data. This key also serves as the “Local” function.

[0]...[9] These keys are used to enter parameters and are only active
when the meter is in the ENTRY mode.

ENTER [

, µH, pF], [k

, mH, n F], [M

, H, µF]. These three keys are
used for entering numeric parameters in the entry mode (e.g. R, L, C
values). The bottom-most key (M

, H, µF) may be used as a general
entry key for entering parameters not listed on the keypad, such as
percent %.

SETUP

STO , RCL The 9216A can store up to nine setups in the memory. To
store the present configuration in memory location # n , press STO [n]

ENTER . To recall a setup, press RCL

CAL ENTER .

CAL Enables a series of internal calibration routines, including
open/short and settling time calibration, output amplitude drive, and
internal self-tests.

BIN# , NOM , LIM These keys are used to enter Binning parameters.
The BINNING LED is on when Binning is enabled and the optional
handler is active.
