PARAMETER MENU

The Low Update Time is the minimum amount of time between display 

updates for the Rate display. Values of 0.1 and 0.2 seconds will update the 
display correctly but may cause the display to appear unsteady. The factory 
setting of 1.0 will update the display every second minimum.

Note: Update time settings apply to both Rate A and Rate B.

LOW UPDATE TIME (DISPLAY UPDATE) 





Module 1 is the programming for the Rate parameters. The Rate A signal is 

applied to Input A, and the Rate B signal is applied to Input B. The Rate values 
are shown with an indicator of

seconds

The High Update Time is the maximum amount of time before the Rate 

display is forced to zero. (For more explanation, refer to Input Frequency 
Calculation.) The High Update Time 

must

 be higher than the Low Update Time 

and higher than the desired slowest readable speed (one divided by pulses per 
second). The factory setting of 2.0, will force the display to zero for speeds 
below 0.5 Hz or a pulse every 2 seconds.

SUM (A+B). Rate C shows the sum of Rate A and Rate B.



DIFFERENCE (A-B). Rate C shows the difference of Rate A and 
Rate B. 



RATIO (A/B). Rate C shows the percentage of Rate A to Rate B.



PERCENT OF TOTAL (A/A+B). Rate C shows the percentage of 
Rate A to the total of Rate A and Rate B.

Set the Display Multiplier to obtain the desired Rate C display resolution. 

For Rate C percentage calculations, the result is internally multiplied by 100 to 
show percent as a whole number. By using a Display Multiplier of 10, 100 or 
1000, along with the proper decimal point position, percentage can be shown in 
tenths, hundredths or thousandths respectively.

The Rate C display indicator in digit 6 may be turned OFF if desired. Rate A 

and Rate B display indicators are always shown.

Note: Disabling Rate C indicator does NOT provide an additional digit for Rate

When Rate C is enabled, this parameter sets the decimal point position for 

Rate A and B display (same position for both), and any setpoint value assigned 
to Rate A or Rate B. If Rate C is disabled, this parameter does not appear and 
separate decimal point positions can be selected for Rate A and Rate B.

This selects the decimal point position for Rate A display and any setpoint 

value assigned to Rate A. This parameter does not appear if Rate C is enabled.

RATE A DECIMAL POSITION



This parameter specifies the number of linear segments used for the Rate A 

Scaling function. Each linear segment has two scaling points which define the 
upper and lower endpoints of the segment. The number of segments used 
depends on the linearity of the process and the display accuracy required as 
described below.

Linear Application – 2 Scaling Points

Linear processes use a single segment (two scaling points) to provide a linear 

Rate display from 0 up to the maximum input frequency. For typical zero based 
frequency measurements (0 Hz = 0 on display), leave

For non-zero based 2 scaling point applications, set
