Warning

Alarm 1 Being Tested – Indicates Alarm Output 1 is in test
mode.

Alarm 2 Being Tested – Indicates Alarm Output 2 is in test
mode.

Pulse Output Being Tested – Indicates Pulse Output is in test
mode.

Alarm 1 Activated – Indicates an alarm has occurred in
response to a condition assigned to Alarm 1 output.

Alarm 2 Activated – Indicates an alarm has occurred in
response to a condition assigned to Alarm 2 output.

Flow Rate Exceeds Display - Flow rate exceeds the flow rate
display capability. Displayed as
ErAtE
on the HRT1 LCD
display. See section 5.5 Error Conditions for more
information.

Flow Exceeds 20 mA Calibration - Flow rate exceeds the 20
mA flow rate upper range value (URV). Analog output will
saturate at 24 mA. Displayed as
EFLo
on the HRT1 LCD
display. See section 5.5 Error Conditions for more
information.

Pulse Rate Overflow - Pulse output exceeds Pulse Frequency
setting. Output pulses will stop during this condition.
Displayed as
EPuLSE

Device Setup

HRT1 Tag – Assign HRT1 serial number

Max Sample Time – Assign the maximum time in tenths of a
second to sample the input frequency. This setting determines
the amount of time the HRT1 will wait for the next input pulse
before returning to 0. Valid entry is 1-80, with 80 = 8
seconds. Default is 1. Changing this setting is only
recommended for low flow applications below 1 Hz. See
section 4.1 Local Configuration for more information.
