2. When tamper attempts are already
incremented, if tamper is reconfigured then
following happens,
If the reconfigured value is greater than tamper
attempts, then the tamper attempts value is
retained.
If the reconfigured value is smaller than tamper
attempts, then the tamper attempts value is
clamped to the reconfigured attempts.
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.
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 all of the settings controlling the Tamper
Detection option:
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 the Attempt Counter to zero.
This option causes a Master Reset of the transmitter,
which is the equivalent to power cycling the device.
This function enables the user to test the Analog
Output measurement at any value over the full
operational range. Click a current value to apply to the
output and verify the measured current on the loop with
a calibrated meter.
Note: This function is only available when Loop mA
(Loop Current mode) is Enabled.
Click the Lock state for access by HART configuration
tools.
If Yes is selected to lock the device, also click” 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.
