• Determine the tamper status of the module
• Determine the reading value reported by the module
• Evaluate the reading value against the high and low audit values to determine if
the reading is high or low
The Portable Interrogator 400 first analyzes the module response to determine if the
communication was completed without errors. If an error is found, The Portable
Interrogator 400 assigns the status as Bad Response, sounds the Bad Response tone, and
flashes the XMIT light red (on-off-on-off-on-off, ½ second each). If no error is found,
The Portable Interrogator 400 determines if the module reported a tamper. If a tamper
condition was reported, The Portable Interrogator 400 assigns the tamper status. If the
module is tamper free, the reading is compared to the high and low audit values that were
sent to The Portable Interrogator 400 from the Route Management software. If the
reading value is greater than the high audit value or lower than the low audit value, The
Portable Interrogator 400 assigns either the High Reading or Low Reading status. If the
reading is within the audit values, The Portable Interrogator 400 assigns a Good Reading
status.
If the reading is within limits, The Portable Interrogator 400 will beep and display a green
XMIT light for three seconds to denote a successful completion of the reading process,
and advance the display to the next meter in the route. If the reading is high or low, the
next step that The Portable Interrogator 400 takes depends on the Settings you give it.
One of the choices is to advance to the next meter in the route if the reading is high or
low. If the setting is chosen, The Portable Interrogator 400 will advance the display to
the next meter. If the setting is not chosen, The Portable Interrogator 400 will keep the
current meter displayed. In either case The Portable Interrogator 400 will beep two tones
for a high meter reading or three tones for a low meter reading. The Portable Interrogator
400 will also flash the XMIT light green for three seconds (on-off-on-off-on-off for ½
second each) to denote a high or low reading in which the display is not advanced.
If The Portable Interrogator 400 assigned a tamper status to the reading, The Portable
Interrogator 400 will sound the special tamper signal and flash the XMIT light yellow
three times (on-off-on-off-on-off, ½ second each). The Portable Interrogator 400 then
shows you the different options you can choose to respond to the tamper report.
