PROGRAMMABLE FUNCTIONS
UNIT PERSONALITY
Functions as a programmable Dual Rate Indicator, with or without speed
ratio, speed difference or draw indication.
PRESETS
Range 0 to ±999999
SCALE FACTORS
Separate 5-digit input scaling for both rate channels. Range 0.0001 to
5.9999.
SCALE MULTIPLIER
Multiplies the actual rate input by 1000, 100, 10, 1, 0.1, or 0.01 to view the
desired number of significant digits on the 6-digit display.
RESET OPERATION
Manual reset via front panel pushbutton or remote “RST” terminal can be
programmed to act on one or both outputs. A separate “RST.A” terminal is
available to provide independent reset of each channel. Front panel pushbutton
reset may be disabled by a switch at the rear of the unit. Reset only applies to
the outputs and has no effect on the sample time or the displayed value.
RIGHT-HAND DUMMY ZEROS
Up to three non-functional zeros may be placed on the least significant end
of the display when the unit is programmed in the dual rate only mode.
UPDATE TIME
The Rate Minimum Update Time is programmable from 0.5 to 16 seconds.
Provides averaging capability for non-consistent pulse spacing. Rate
Maximum Update Time will vary with the minimum time selected.
RATE CONVERSION FACTOR
Provides easy display conversion for readout in Rate Per Second, Rate Per
Minute, or Rate Per Hour.
DECIMAL POINT & LEADING ZERO BLANKING
Decimal point programmable to desired location. Leading zero blanking,
when selected, begins with second digit to the left of the decimal point.
OUTPUT TERMINATION MODES
Terminate at Manual Reset
Terminate at Manual Reset End
Terminate after Time Delay
Boundary
For positive preset value: Output terminates when Display is less than
Preset.
For negative preset value: Output terminates when Display is greater
than Preset, (i.e. more positive).
Note: In any of the above modes, the unit may be programmed for “Reverse
Phase” operation which complements the logic state of the output.
TIMED OUTPUTS
Programmable from 0.01 to 599.99 seconds. Accurate to ±(0.01% + 10
msec.).
FRONT PANEL LOCKOUT MODES
When the “Program Disable” control input is activated, the ability to
change front panel programmed functions will be prevented as per the
following modes:
Complete Front Panel Disabled
Presets Enabled Only
Scale Factors Enabled Only
Presets and Scale Factors Enabled
Note: Manual Reset may be independently enabled or disabled in any of the
above modes.
SELF-TEST
Performs a complete check on the display and output circuitry along with a
functional check on the CPU.
