The Peak Picker function can be used to monitor the highest temperature measured
by the thermometer. This feature is useful especially for moving targets and/or where
the target is obscured partially e.g. a steel slab on a rolling mill where parts of the
surface are covered with scale. The 'clean' area will be at the higher (i.e. true)
temperature. The Peak Picker used in Landmark Technic processors has the
following features. Refer to Fig. 10.
OFF delay:
Mode:
In 'Hold' mode, at the end of the 'OFF' delay, the temperature
output value is held constant until the temperature input next
rises above the threshold level.

Refer to Fig. 11. The Track and Hold time function is useful especially for measuring
intermittent processes e.g. items on a conveyor belt. The presence of a 'hot' object
can be used to activate the 'Track' function, which causes the output to display the
temperature of the object. When the object moves from the measurement area, the
'Track' function can be switched off and the temperature value held until the next 'hot'
object appears.

Averager
Refer to Fig. 12. The Averager time function can be used to 'smooth' the temperature
output signal in relation to the temperature input. The averager response can be
adjusted to suit your application. With a fast response speed, the temperature output
signal tracks the input signal closely, any rapid fluctuations in the input are reflected
in the output. With a slow response speed, the temperature output signal is much
smoother, displaying more the 'trend' of the input signal rather than rapid changes.

Command response time
Landmark Technic
Command response time
This is the time taken between the end of the last character of a command and the
beginning of the first character of the reply. This time is independent of the selected
baud rate.
User Guide
This is the time taken between the end of the last character of a command and the
beginning of the first character of the reply. This time is independent of the selected
baud rate.
All commands are serviced within 20ms.
System Communications Timing Data
All commands are serviced within 20ms.
Command reply time
System Communications Timing Data
Command reply time
Inter-command timing
This is the time taken by the LM Technic reply. It is directly related to the selected baud
rate and the number of characters in the reply.
Inter-command timing
This is the time between the end of the last character of a command received by the
LM Technic and the end of the last character of its response i.e. the period when the
LM Technic is unable to take a command because it is still processing a previous one.
This is the time taken by the LM Technic reply. It is directly related to the selected baud
rate and the number of characters in the reply.
This is the time between the end of the last character of a command received by the
LM Technic and the end of the last character of its response i.e. the period when the
LM Technic is unable to take a command because it is still processing a previous one.
This is the command response time + command reply time.
NOTE
Use of the IFO command, which will involve long replies, will
disrupt internal timing and affect time function processing.
This is the command response time + command reply time.
For RS232C at 9600 baud, assuming a reply of 20 characters maximum, the
inter-command time is 41ms.

RS232C
The maximum cable lengths are, to a great extent, dependent on baud rate and cable
type. Generally a lower baud rate will give reliable communications over a longer
length of a given cable type.
