BEKA BA524D, Manual

Page: 7 / 23

Display Description of function
'SEt' Calibration of display using internal
references.
Enables the zero and span of the
indicator to be adjusted without the
need for an accurate input current or
disconnection from the 4/20mA loop.
See section 5.6
'Cond' Indicator conditioning
This function provides access to a
sub-menu enabling the mains (line)
frequency to be selected and the
internal references to be calibrated.
Because these parameters will alter the
indicator display, they are contained in
a sub-menu to prevent inadvertent
adjustment.
Caution
If the mains filter frequency is
changed, the indicator display
and internal references (if used)
must be recalibrated.
See section 5.7
'FrE' Frequency rejection
Defines the mains (line) frequency at
which the indicator has maximum ac
rejection. 50 or 60Hz may be selected.
This function must be set before the
instrument is calibrated as it affects the
indicator display.
See section 5.7.1
'rEF' Calibration of internal references
The instrument contains two references
representing a 4 and 20mA input.
These enable the BA524D display to be
calibrated without the need for an
external calibrator, or disconnection
from the 4/20mA supply. See SEt
function.
If the SEt or C--P functions are to be
used, the internal references should be
periodically calibrated.
See section 5.7.2
Display Description of function
'C - - P' Function of P push-button
The BA524D may be programmed to
display the input current in milliamps or
as a percentage when the
P
push-button is operated.
See section 5.8
'COdE' Security code
Defines a four digit numeric code which
must be entered to gain access to
programmable functions. Default code
0000 disables the security function and
allows unrestricted access to all
programmable functions.

section 5.9
