Parameter Descriptions
Parameter 0 Exit to Running Mode
When parameter 0 is selected in Parameter-Selection Mode, the unit will return to Running Mode
and display the running value. This should be selected once changes to parameters are
completed.
Parameter 1 Model Number (Read Only)
This is a number which represents the base model number for the product. For the DTM8000,
the model code is 80.
Parameter 2 Software Build (Read Only)
The software build is a code which identifies the software version of the unit.
Parameter 3 Hardware Version (Read Only)
The hardware version is a code which identifies which hardware was used to build the unit.
Parameter 4 & 5 Serial Number, Major & Minor (Read Only)
These parameters are reserved for future use as an electronic serial number and are unique to
each manufactured unit.
Parameter 10 Operating Mode
This parameter defines the basic mode of operation for the entire unit. It determines if the unit
is measuring rate, time, or count information. The following modes are available:
Mode 1 Rate Mode
Rate mode displays measurements in rate units such as RPM, Gallons per Hour, or Feet
per Second.
Mode 2 Time Mode
Time mode displays measurements in time units using the format AA:BB. By default
AA:BB represents minutes (AA) and seconds (BB). Optionally, it can be configured to
represent hours (AA) and minutes (BB) or other user-defined units with a 1:60 relationship.
Mode 3 Up Counter
Counter modes (3 5), display measurements in pulse counts or user-defined units which
are proportional to pulse count. In these modes, the DTM8000 will count the pulses which
are applied to the S1 input and display the related value. In this mode, each input pulse
increments the counter.
Mode 4 Down Counter
Same as Mode 3 above except each input pulse decrements the counter.
Mode 5 Up / Down Counter
Same as Mode 3 above except each input pulse either increments or decrements the
counter depending upon the state of Signal Input #2 (S2). If S2 is tied to common, the
counter is incremented; otherwise, it is decremented.
Parameter 11 Display Intensity
This parameter adjusts the intensity of the LED display digits in the front panel of the unit. The
values of 0 31 correspond to a gradual change from very dim to very bright. This is often useful
when used in the same panel as other pieces of equipment with LED displays and a uniform
display brightness is desired.
Parameter 14 Input Triggers / Prescale
This parameter determines how the S1 signal input is processed. It specifies which signal edge
is used for the measurements and the value of the internal frequency divider or prescaler.
Modes 3 and 4 should only be used if the input pulse rate exceeds the unit's maximum native
pulse rate (see specifications for details); otherwise, timing and counting calculations may
become sluggish and unnecessarily inaccurate.
Mode 1: Every Rising Edge, No Prescaler
In this mode, the signal input is measured at every rising edge.
Mode 2: Every Falling Edge, No Prescaler
In this mode, the signal input is measured at every falling edge.
