Unit Receives No Return Echo Due To:
C,F,E - foam on liquid surface - Use stilling well (open channel flow)
B - target beyond
MAX RG - Recalibrate
E - calibration error -
ISB No selected in SPECIAL FUNCTIONS
and instrument has an optional ISB
G - sensor damaged
Wiring Problems Due To Sensor Cable:
A,C,F, - open circuit - Measure continuity (5K Ohms max.)
B,F - short circuit - Check connections
F - too long (max 500 ft., 150 m)
C - bundled/run in conduit with power
cable
C - sensor ground shorted to
conduit/enclosure
- Insulate
A - extended with wrong type of wire - Use RG62A/U coaxial only
C - close to high voltage/large motors
G - AC chassis/ground missing on
instrument power connections
Non-Linearity Due To:
H - Vapour - Dissipate fumes, Calibration in-situ
H - zero not set accurately - See “Zero Positioning of Sensor”
H - wrong flume, or K&n selected (
FLOW
mode)
- Select correct flume
D,E - calibration error -
ISB Yes selected in SPECIAL FUNCTIONS
menu and instrument does not have an ISB
FUSE REPLACEMENT
1. Turn OFF power
2. Loosen 2 Phillips corner screws and remove power module from the chassis.
3. Locate fuse on Power Board
4. Replace fuse with 2 Amp/250V, 5 x 20mm fuse
5. Reinstall power module in the chassis.
