Myron L D-6 - Manual (Page 6)

I. GENErAL WArNINGS AND CAuTIONS
For your own safety and the safety of your patients follow these
important safety instructions as well as other safety instructions noted
throughout this operation manual.
WArNING: statements alert the user that serious adverse reactions for
the patient are associated with related use or misuse.
CAuTION: statements alert the user that the related use or misuse of
the device could cause it to be damaged or malfunction.
WArNING: Read this entire operation manual before using a Digital
Dialysate Meter™.
WArNING: When using a Digital Dialysate Meter™ to check the
conductivity or pH of dialysate, ALWAYS perform a calibration
check of the instrument for those measurement functions at the
beginning and end of each work day or more often if required by
your clinic’s internal procedures.
• See Calibration, pg. 16, for instructions.
WArNING: When using a D-6 to verify the complete removal of residual
oxidizing germicides, such as chlorine, ORP mV reading should be
as low as possible. Generally, an ORP reading of < 275 mV is a good
indicator that there is very little residual oxidizer remaining. However,
it is recommended that a target reading matching or close to the ORP
value measured at the output of your RO system be sought.
WArNING: Because pH measurements require temperature
compensation, ALWAYS fill both the pH sensor well and
conductivity cell with sample.
• The Digital Dialysate Meter’s™ temperature sensor is located in
the conductivity cell.
WArNING: When measuring with a Digital Dialysate Meter™, DO
NOT press the CAL key unless instructed to by a procedure in this
manual.
• This will activate the Digital Dialysate Meter’s™ calibration mode
(the word CAL will appear at the top of the display) and could
inadvertently change the calibration of the instrument and alter
the accuracy of measurements.
• If you do accidentally activate CAL mode:
• DO NOT press either the UP, DOWN or CAL keys.
• Re-press the desired parameter function key to return the instrument
to measurement mode.
