PROGRAMMABLE FUNCTIONS
UNIT PERSONALITY
Functions as a Counter and Rate Indicator.
PRESET(S)
Range 0 to ±999999
SCALE FACTORS
5-digit input scaling, Range 0.0000 to ±5.9999.
SCALE MULTIPLIER
Multiplies the contents of the 9-digit internal counter by a factor of 1, 0.1, 0.01,
or 0.001 to view the desired number of significant digits on the 6-digit display.
COUNTING MODES
Count with Inhibit
Count with Up/Down Control
2-Input Anti-Coincidence Add
2-Input Anti-Coincidence Add/Subtract
Quadrature
Quadrature X4
RESET ACTION
Reset-to-Zero: Output activates when count equals the preset value. Counter
returns to zero when reset.
Reset-to-Preset: Output activates when count equals zero. Counter returns to
preset value when reset.
RESET MODES
Manual Reset
Automatic Reset at Preset
Automatic Reset after Output Time Delay
Note: Manual reset via front panel pushbutton or remote “RST.” terminal can
be programmed for momentary or maintained action. Front panel reset may
be disabled by a switch at the rear of the unit.
SELF-TEST
Performs a complete check on the display and output circuitry along with a
functional check on the CPU. Self-test is non-destructive and may be
performed during a process without losing counts.
FREQUENCY DOUBLING
Registers counts on both edges of input signal.
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.
RIGHT-HAND DUMMY ZEROS
Up to three non-functional zeros may be placed on the least significant end
of the display.
OUTPUT TERMINATION MODES
Terminate at “other” Output Start (Gemini 2000 only)
Terminate at “other” Output End (Gemini 2000 only)
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.
OUTPUT TIME DELAY
Programmable from 0.01 to 599.99 seconds. Accurate to ±(0.01% + 10 msec.).
SAMPLE TIME MULTIPLIER
Multiplies the basic one-second data sampling time by 1, 2, 5, 10,
20, or 50. Accurate to ±0.01%.
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 Disable
Preset(s) Enabled Only
Scale Factor Enabled Only
Both Preset(s) and Scale Factor Enabled
Note: Reset may be enabled or disabled in any of the above modes.
