PR
- Peak Picker Reset (Write Only)
This function is used to reset the Peak Picker. It is a write only command and no value is given. By
sending the PR Command, with or without a message value, a Peak Picker reset is performed.
Message Value Range: Not Applicable
Actual value: Always returns #A0PR<CR>, where A =the sensor
DR
– Peak Picker (Read / Write)
Sets the peak picker decay rate. Zero (0) sets the unit to never decay. Otherwise decay is in selected
measurement units, °F or °C. See Section 5.10.1 D.R. – Decay Rate Function, page 100 for more
information.
For Sensors with firmware versions 1.02 and higher
Scaled Message Value Range: 0 to 30000 (°F per second times 100)
Scaled Message Value Range: 0 to 16666 (°C per second times 100)
Actual Value: .01 to 300.00 (°F per second), except 0 which = Off
Actual Value: .01 to 166.66 (°C per second), except 0 which = Off
Sensor Firmware Version Operation Summary
Original Sensors with firmware versions less than 1.02 have unit-less degree units that
range 0.00 to 300.00 for both F and C unit’s selection. For those Sensors, the following
operation applies.
Sets the peak picker decay rate. Zero (0) sets the unit to never decay. Otherwise decay
is in °F or °C per second.
Scaled Message Value Range: 0 to 30000 (°F or °C per second times 100).
PS
– Peak Picker Auto Reset (Read / Write)
Selects Peak Picker Auto Reset operation
Scaled Message Value Range: 0 to 2
Actual Value: .0 to 2: Zero (0) Sets Auto Reset to Off: 1sets it to On. (2 is reserved for future use).
PK
–Peak Picker Reset Below Temperature (Read / Write)
Sets the temperature below which the peak picker signal conditioning is in reset or direct reading
mode. Sensor is measuring temperature without peaking action in this mode. Function is used with
Auto Peak Picker Reset.
Message Value Range: Unit’s Zero Scale Temperature to Unit’s Full Scale Temperature (°F or °C)
PD
–- Peak Delay (Read / Write)
Sets the delay time before Peak Picker action starts.
Message Value Range: 0 to 1000 – Zero (0) turns off any delay. Above 0, this is a scaled value. (Scaled
input above 0 = actual value times 100).
Actual Delay Range in Seconds:
0.010 to 10 seconds.
