Description
Values
1.P
Number of display digits
.
4, 5, 6
2.P
Number of digits after decimal point
. Defines the position of
the decimal point.
0-5
3.P
Display resolution
. 1-200
4.P
First two digits of full load
. 00-99
5.P
Digital filter
. If x is entered, the filter averages 2
x
samples.
0-5
6.P
Number of conversions per second
.
3, 7, 14, 28, 57, 70
7.P
No-motion samples
. If x is entered, no-motion samples are 2
x
. 1-7
8.1
Auto-zero maintenance
.
0=NO 1=YES
8.2
Auto-zero at power up
.
0=NO 1=YES
8.3
Dual digital filter
(Antiflicker)
0=NO 1=YES
8.4
Automatically clear A/D converter error
(Error 05).
NO specifies that, when the A/D converter is enabled, errors are
automatically cleared when the cause is no longer present.
YES specifies that A/D converter errors should remain on the
display until the operator presses
ESC
.
0=NO 1=YES
8.5
(Reserved for future use)
8.6
Leading zero blank
.
0=NO 1=YES
8.7
Load cell amplifier gain adjustment (A/D Gain)
.
2mV/V setting allows maximum utilization of 1.75mV/V
4mV/V setting allows maximum utilization of 3.75mV/V
0=2mV/V
(1.75mV/V utilization)
1=4mV/V
(3.75mV/V utilization)
8.8
AC/DC excitation
.
AC sets load cell excitation to AC, and specifies that polarity
excitation should be switched at the conversion rate. Switching
excitation results in more stable zero.
DC sets load cell excitation to DC.
0=AC 1=DC
8.A
Zero range
. Some operations, including taring and printing, are
only active within the zero range.
0=2% 1=10%
8.b
Dual interval or range
. This parameter is not relevant if
0.P
=00.
0=interval 1=range
8.c
Unit selection.
Specifies the weight unit.
kg=kilograms
lb=pounds
0.P
First two digits of weighing range, defining the limit
between the 2 weighing ranges
, the lower display division is
automatically selected. If set to 00, disables interval / range.
00-99
