For accurate ORP measurements, the surface of the electrode must be

clean and smooth. Pretreatment solutions are available to condition

the electrode and improve its response time (see "Accessories" section).

Notes:

• When the reading is out of range, the display will flash the closest

full-scale value.

• If using pH electrode while in mV mode, the meter will measure

the mV generated by the pH electrode.

MEM & MR FUNCTIONS

From normal measurement mode, pressing the MEM key will freeze

the readings on the display and store into internal memory the

current values (pH and temperature, or mV and temperature)

together with “condition” and buffer segments.

The MEM tag blinks and the display remains frozen until the MEM

key is pressed again.

Note

: While in MEM mode, the user can switch between pH and mV

by pressing the RANGE key.

A stored value can be recalled by pressing MR: the display will show

the value, together with the RCL & MEM tags, as long as the MR key

is pressed.

Note

: Pressing MR, only the range that was active at the time MEM

was pressed is shown.

BACKLIGHT FEATURE

The meter is provided with a Backlight feature,

which can be easily toggled on and off through

the keyboard by pressing the LIGHT key.

Note

: The backlight automatically shuts off after approximately 1 minute

with no buttons pressed.
