REV. 16-SIP/SRP
f) Sensor may be contaminated. Remove probe, wipe
off or clean with a solvent. Reinsert.
g) Using a different gas or gas mix than the meter
was specified and calibrated for.
h) If a Remote Style Meter (SRP), be sure Serial
Numbers of Junction Box and Remote Electronics
are identical (if not, errors in calibration are in -
evita ble). To confirm, verify that Junction Box
Serial Number Tag has identical Serial Numbers
to Tag on Remote Enclosure.
i) Meter may appear to be reading low if user is
comparing Sage flow meter readings (SCFM) to
an uncorrected volumetric device (ACFM). For
example, at constant volume, an increase in gas
temperature will lower the mass flow (SCFM).
That is completely normal.
j) On most models, the Totalizer will not start count-
ing for 10 seconds after power up so any flow data
will not be accumu lated during this time.
k) Insufficient power supply—most products require
minimum 100 ma.
l) Excessive load on the 4-20 ma. (To check if prob-
lem is due to 4-20 ma output device, temporarily
remove device, and observe if display reads as
expected).
SYMPTOM:
Totalizer can take up to 10 seconds to
update its reading when flow meter is first powered
up, or a channel is changed.
CORRECTIVE ACTION: None. This slight delay is com-
pletely normal.
SYMPTOM:
Display does not have power
POSSIBLE CAUSE: Mis-wiring
SYMPTOM: 4-20 mA output not tracking the flow rate
display
POSSIBLE CAUSE:
a) In normal operation (Self Powered) B4 and B5
must be jumpered to supply power to loop. See
pages 19 and 22.
b) In Externally Powered mode, the jumper must be
removed. Verify that 9 to 27 Volts DC is supplied
to externally power the loop as per page 19 or 22.
