Tamper Latency
Displays the current setting of the Tamper Latency (0-60
seconds).
Tamper latency is the time period for which
the tamper alarm remains set in response of
command 48 and reflected as “Tamper Alarm” Device
Status condition.
Max Attempts
Displays the current setting for the Tamper Maximum
Attempts configuration. This is the maximum number of
tamper attempts to be permitted during one Latency
period before setting the Tamper Alarm status.
Configure
Tamper Mode
Configure all of the settings controlling the Tamper
Detection option. Selections include:
Select Tamper Mode: enable or disable tampering
detection. When enabled, the “Tamper Counter” will
keep track of the number of times an attempt is
made. After the configured “Max Attempts”, an alarm
status is generated.
Tamper Latency:
Configure the desired latency (in seconds) for the
Tamper detection.
Maximum Attempts:
Configure the maximum number of tamper attempts
allowed before the device sets the Tamper Alarm
status
Reset Tamper
Counter
Reset the Attempt Counter to zero.
Master Reset
Selecting this option will cause a Master Reset of the
transmitter, which is the equivalent to power cycling the
device.
Loop Test
This function enables the user to test the Analog Output
measurement at any value over the full operational range.
Select a current value to apply to the output and verify the
measured current on the loop with a calibrated meter.
Note that this function is only available when “Loop mA”
(Loop Current mode) is Enabled.
Lock/Unlock
Device
Select the Lock state for access by HART configuration
tools.
If “Yes” is selected to lock the device, also select “Yes” or
“No” to choose whether or not the lock is “permanent.” If
the lock is not permanent, it will be cleared on power cycle
or Master Reset of the device.
If “Yes” is selected to unlock the device, the lock state will
be cleared.
