Notes:

• If  the  reading  is  out  of  range,  the  full-scale  value  (100.0  for 

MTC

/

ATC

  mode  or 

400.0 for uncompensated TDS) will be displayed blinking.

• If the SHIFT&RANGE/FIXED keys are pressed to freeze the LCD range and the reading 

goes  out  of  range,  the  full-scale  value  of  the  frozen  range  will  be  displayed  blink-
ing.

NaCl MEASUREMENTS

• Press the RANGE/FIXED key to enter NaCl measurement mode.
• The instrument will display the NaCl reading on the primary LCD and the temperature 

on the secondary LCD, along with the reference temperature.

AUTORANGING

The EC and TDS scales are autoranging. The meter automatically sets the scale with 
the highest possible resolution.
By pressing the SHIFT&RANGE/FIXED keys, the autoranging feature is disabled and the 
current range is frozen on the LCD. The “Auto” “OFF” (autoranging disabled) message 
will  be  displayed  on  the  LCD  for  a  few  seconds.  To  restore  the  autoranging  option, 
press  the  SHIFT&RANGE/FIXED  keys  again.  The  “Auto”  “On”  (autoranging  enabled) 
message will be displayed on the LCD for a few seconds.

Note

: Autoranging  is  automatically  restored  if  the  range  is  changed,  if  the  setup  or 

calibration modes are entered and if the meter is turned off and back on again.
