2) Dip the probe into the sample beyond the upper steel band
(utilize the fill line on the outside of the probe guard for
reference).
3) Allow time for the reading to stabilize. Note the reading on the display.
The clear yellow protective probe guard must be attached during
measurement. Erroneous results will occur while the probe guard is
removed.
5.2 Automatic and Manual Ranging
The CON 700 automatically selects the optimum range in which your
readings appear. Refer to TABLE 1 for a list of the available ranges.
To turn-off automatic ranging, press . MEAS will flash, indicating
that manual ranging is active. To manually select the next range,
press again. After range 5, automatic ranging is resumed.
For example, a reading of 465 μS will automatically settle in range 3.
Using manual range advancement this will read as 0.47 mS in range 4,
and 0.5 mS in range 5. For best resolution, use auto-ranging.
5.3 HOLD Function
For prolonged observation of a reading, press during
measurement mode to freeze the display. The “HOLD” indicator will
display when the reading is held. To release the held value and
resume measurement, press again or insert the held value into
memory by pressing .
5.4 Storing and Recalling Data
The CON 700 can retain up to 100 data points into memory for
later retrieval.
1) In the measurement mode, press to insert the measured value
into memory. The stored memory location value (StO) is briefly
displayed.
