GETTING STARTED 

 

3.1

 

Unpacking 

Your instrument is shipped with a pH electrode, a temperature 
probe, buffer solution pH 7.00 , buffer solution pH 4.01 and this 
manual.  Check  the  items  carefully  and  contact  the  place  of 
purchase immediately if anything is missing or damaged.

Setting Up 

3.2.1

 

Pull  the  latch  of  battery  cover  located  at  bottom  rear 
of  instrument  and  pull  out  the  battery.    Unwrap  the 
battery, attach the battery clip onto it and put it back 
into  the  battery  compactment.    Finally  close  the 
battery cover.   

3.2.2

 

Plug  the  temperature  probe  and  pH  electrode  into 
their  respective  connectors  on  the  side  of  the 
instrument.  

3.2.3

 

Next,  you  must  calibrate  the  instrument.  Follow  the 
calibration  procedure  in  step  4.  Always  switch  on  the 
instrument  for  about  10  minutes  to  allow  the  internal 
circuitry  to  stablize  before  taking  any  calibration  or 
measurement 

4. 

CALIBRATION PROCEDURE 

To  keep  measurement  accurate  and  precise,  it  is  best  to 
calibrate  the  instrument  each  time  before  a  series  of 
measurements.  Use standard buffer solution with temperature 
coefficient  as  in  Buffer  Solution  Reference  Table  (Page  16). 
Prepare  one  distilled  or  de-ionized  water  for  rinsing  and  two 
sets  of  buffer  solution,  one  for  rinsing  and  the  other  for 
calibration.    This  will  prevent  carry-over  of  solution  during 
calibration.
