MAINTENCE & TROUBLESHOOTING
The RHW Series 2 Full Flow is built around the most current technology and high grade components.
All parts have a 1 year factory warranty so if the unit is new, do not attempt to alter or replace any of
the parts without consent of the factory as this may void the warranty.
As with all electronic systems, do not use when inclement weather is present. Also keep all parts from
water.
Charging
The two universal chargers for the SH and HC are interchangeable and can be used on either of these
devices. When connected, the LED indicator light on the charger will show green when the battery is
half charged to fully charged, and will show red when charging from a deeply discharged battery. Do
not attempt to replace any of the battery packs with a non-factory replacement.
The printer charger is specific for the printer only. It is labeled “PRINTER”. Do not use the printer
charger to charge the HC or SH. Both the printer and printer charger have LED indicator lights. On the
charger, the light will be green when it is plugging into the wall. On the printer, the led will flash when
the charger is connected to the printer. After the charger determines the battery requires charging, the
led on the printer will turn to solid red. Once the battery is fully charged, the led on the printer will turn
solid green.
Filters
The zero filter is clear conditions on the sensor head. Ensure the magnetic band clamp is not blocking
the beam and that the sensor head is not attached to the vehicle when you are asked to insert the filter.
The reference (verification) filter contains a 12.5mm diameter piece of tinted glass. If during the filter
verification test, the filter is reading higher than normal, most likely the filter glass is dirty and
requires cleaning with a small dry cloth or q-tip. If during the filter verification test, the filter is reading
lower than normal, most likely the filter glass has degraded and would need to be returned to the
factory for recertification.
OPTICS SET
The set consists of the transmitter and receiver. The transmitter has 6 pins and the receiver has 5 pins.
It is best to periodically clean the lenses with a dry clean cloth. Depending on use, you may have to
clean the lenses daily. There are adjustment potentiometers in the optics that adjust the gain of the
digital signals. Note : do not adjust these without contacting the technical support as you can render
your meter inoperable.
