ruLES of OPErATION
A. Operation
Using the instrument is simple:
•
Individual Cond/Res/TDS or multiple parameter readings may
be obtained by filling the cond. cell or the entire sensor area.
•
Rinse the pH/ORP sensor well (D-6) and/or conductivity cell
with test solution 3 times and refill. Temperature and/or
measurement extremes will require additional rinses for
maximum accuracy.
•
Press the desired measurement key to start measurement.
Pressing the key again restarts the 15 second auto “off” timer.
•
Note the value displayed or press the MS key to store the
reading (ref. Memory Storage, pg. 25). It’s that simple!
B. Characteristics of the Keys
•
Though your Dialysate Meter has a variety of sophisticated
options, it is designed to provide quick, easy, accurate
measurements by simply pressing one key.
•
All functions are performed one key at a time.
•
There is no “off” key. After 15 seconds of inactivity the
instrument turns itself off (60 seconds in CAL mode). User
adjustable up to 75 seconds.
•
Rarely is it necessary to press and
hold a key (as in
Procedure to Select a Solution, pg. 15; or Conductivity or TDS
Calibration, pg. 19).
C. Operation of the Keys (See Instrument Illustration on pg. i)
1. Measurement Keys in General
Any of the 5 measurement keys in the upper part of the keypad turns on
the instrument in the mode selected. The mode is shown at the bottom
of the display, and the measurement units appear at the right. Pressing
a measurement key does this even if you are in a calibration sequence
and also serves to cancel a change (ref. Leaving Calibration, pg. 18).
2. COND, RES and TDS Keys
These 3 keys are used with solution in the Conductivity Cell.
Precautions:
•
While filling cell cup ensure no air bubbles cling on the cell wall.
•
If the proper solution is not selected (KCl, NaCl or 442), refer
to Why Solution Selection is Available, pg. 15 and Procedure
to Select a Solution, pg. 15.
a. COND Key
Solution to be tested is introduced into the conductivity cell and a
press of
displays conductivity with units on the right. On the left
is shown the solution type selected for conductivity.
