Settings & Display
1. DIP Switch
The DIP switch settings are explained on the next page.
2.
Sensitivity Setting
The 10-position rotary switch allows for adjustment of detection threshold.
The sensitivity threshold increases from position 0 (lowest setting)
through 9 (highest setting). Typical applications require a setting of 3 or 4.
The rotary adjustment must be set to a specific/whole number.
There are no half settings.
3. Power / Loop Fault Indicator (Green LED)
Normal Operation
on
Upon power up, the detector
initializes by automatically tuning to
the loop. The green LED indicates
that the detector is powered and
operational.

5. ULTRAMETER
TM
Display
The display shows the sensitivity setting required to detect a vehicle near the loop. To use this feature,
observe the display while a vehicle is moving into position near the loop, note the number displayed,
then adjust the sensitivity setting to the displayed position. The display will adjust from
9 for a weak signal to 0 for a very strong signal. During normal operation, when a vehicle is not on
or near the loop, the display is blank. The effects of cross-traffic interference can be observed on the
display when the sensing area is vacant.
6. Frequency Count / Reset Button
Press and release the frequency count button and count the number of flashes on the red LED.
Each flash represents 10 kHz. Following a frequency count cycle, the detector re-initializes.
