With the probe out of
the sample to be tested,
depress the pressure-sensitive
switch once and then
again when EMCEE is displayed.
The display will scroll
through the test operation,
and the new conductivity
data should read 0.
The temperature of the
environment will be displayed.
If a number other
than 0 is displayed,
this probably is an indication
that the probe is contaminated
and should be cleaned.
See section 9 of
the written standard
on cleaning procedures.
Over-range check.
Conductivity is greater than
2,000 picosiemens per meter.
With the probe out of
the sample to be tested,
depress the pressure-sensitive
switch once and then
again when EMCEE is displayed.
When the red LED stops
blinking and remains on,
short the outer conductor to the
inner conductor of the probe.
A thumb or finger touching
the tip of the probe
to short the two
conductors is sufficient
and is perfectly
safe to the operator.
At the end of the test period,
when the LED extinguishes,
the display will scroll
through, and in lieu
of displaying a numerical
value for the conductivity,
the display will read
"Over," thus indicating
that the measurement
is over range
and the meter is
operating properly.
