Parameters

Display units: The units to use when displaying mass. Available units are

μg (displayed as ug), mg, g, kg,

ounces (oz), pounds, (lb), and stone (st). See Section 2.1 for details.

Averages: Number of points to use when reading weight. The choices available are 2, 4, 8, 10, 16, 32,

50, 64, 100, and 128. The default is 50.

ADC speed: This parameter selects between the two data rates on the ADS1232, which are called

The actual data rate of the ADS1232 depends on the frequency of the master clock, f

data rate is f

information.

The default setting is low-speed mode.

Calibration weight: This parameter gives the expected mass of the calibration weight used in the

calibration procedure (Section 2.3). The calibration mass can be given in any of the available units, in

three significant figures. The unit is independent of the display unit.

Each digit in the mass is adjusted separately. The currently-selected digit flashes, and can be adjusted

with the PARM buttons. The VALUE buttons are used to select the digit. The unit is adjusted in the same

manner, and flashes when selected.

When the unit is changed, the value changes to the equivalent mass in the new unit.

Channel Selection: This parameter selects between the two analog input channels. Channel 1 uses

either the header or the IN1 connections on the terminal block. Channel 2 uses the IN2 connections on

the terminal block.

Offset calibration: This screen has the same function as it does in Analysis mode. See Calibration for

information.

Save parameters: This screen allows the settings of the ADS1232REF to be stored in flash memory. It

functions the same as it does in Analysis mode. When either PARM button is pressed on this screen, the

ADS1232REF saves its settings to flash memory. These settings are loaded from flash memory when the

board is reset or powered on. All operating parameters are saved, including scale calibration settings,

voltage reference, display mode, and units.

Version number: This screen displays the version number of the ADS1232REF firmware.

(1)

The ADS1232REF cannot detect the frequency of the ADS1232 master clock, so it cannot display the actual data rate of the ADS1232

device.
