V. RULES of OPERATION
A. Operation
Using the instrument is simple:
• IndividualCond/Res/TDSormultipleparameterreadingsmay
 beobtainedbylling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rell.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lling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.
