CODE 44 - NUMBER OF COUNT EDGES
The Gemini can be programmed for either single edge or two edge (doubling)
counting. The number of count edges cannot be set when the count mode is
programmed for quadrature X4 operation (the Gemini will ignore any attempt to
enter function command code 44 when set for quadrature X4) .
[44 1] SINGLE EDGE COUNTING - The unit counts on the negative going
(falling) edge of the count input signal. The count mode descriptions
describe how each mode uses this method of edge counting.
[44 2] TWO EDGE COUNTING - This mode is used when doubling of the
count signal input is required. The unit counts on the positive going
(rising) edge of the count input signal, as well as, the negative going
(falling) edge.
CODE 45 - SCALE MULTIPLIER
There are four scale multiplier values that are available. They are: 1; 0.1; 0.01;
and 0.001. They effectively divide the internal count value by 1, 10, 100, and
1000 respectively, to yield the displayed count value. Note: Use of a small scale
multiplier in conjunction with a small scale factor could cause the internal count
value to be exceeded before the 6-digit display value is exceeded. See “Overflow
Indication” section for more details.
[45 1] SCALE MULTIPLIER VALUE OF 1 - This value multiplies the
internal count by 1.
[45 2] SCALE MULTIPLIER VALUE OF 0.1 - This value multiplies the
internal count by 0.1. (Effectively divides by 10.)
[45 3] SCALE MULTIPLIER VALUE OF 0.01 - This value multiplies the
internal count by 0.01. (Effectively divides by 100.)
[45 4] SCALE MULTIPLIER VALUE OF 0.001 - This value multiplies the
internal count by 0.001. (Effectively divides by 1000.)
CODE 46 - DECIMAL POINT & LEADING ZERO BLANKING
There are six basic modes of decimal point placement on the Gemini. The
decimal point is placed to the right of the display digit that corresponds to the
mode identifier. (The right most decimal point, digit 1, is never turned on.) A “-”
sign in front of the mode identifier will inhibit leading zero blanking. The
absence of the “-” sign will enable leading zero blanking.

CODE 51 - RESET MODES
The Gemini has six different reset modes. They are: Manual Reset to Zero;
Manual Reset to Preset; Automatic Reset to Zero After Output Time Delay;
Automatic Reset to Preset after Output Time Delay; Automatic Reset to Zero at
the Beginning of the Output Time Delay; and Automatic Reset to Preset at the
Beginning of the Output Time Delay. (Note: For the Gemini 2000, reset to preset
modes reset to preset 2 and Output refers to Output 2.) There are also two
methods by which manual reset can act on the unit (reset must be enabled) . The
first is a “maintained” reset action where the unit is held at reset as long as the
reset terminal is held low or the front panel reset button is pressed. The second is a
“momentary” reset in which the unit resets when reset is activated and
immediately starts counting even though the terminal may still be low or the reset
button may still be pressed. (Note: In momentary reset, the display will not
update until reset is released, but internal counting and all other functions are
operative.) A “-” sign in front of the code identifier will provide for
“momentary” reset, and the absence of a “-” sign will give “maintained” reset.
[51 1] MANUAL RESET TO ZERO (RTZ) - Manual reset to zero is
accomplished by pulling remote reset to ground, or if the front panel reset
is enabled, by pressing the front panel reset button. Reset is “maintained”.
[51 2] MANUAL RESET TO PRESET (RTP) - Manual reset to preset is
accomplished by pulling reset to ground, or if the front panel reset is
enabled, by pressing the front panel reset button. Reset is “maintained” .
