INTRODUCTION
Sper Scientific is pleased to offer the following line of bench
-top meters:
Model 860031 (pH/mV)
Model 860032 (Conductivity/TDS/Salinity)
Model 860033 (Water Quality)
Please note that the meter itself is identical in each of the
above models. Each model can be used for pH/mV,
Conductivity/TDS/Salinity or Water Quality depending on
the probe used.
To utilize your meter under additional parameters, please
refer to the list of probes in OPTIONAL ACCESSORIES on
page 65.
Instructions for all three models are contained within this
manual. Refer to the TABLE OF CONTENTS for the
subsection within MEASUREMENT PROCEDURES that
corresponds to the particular parameter you are measuring.

To enter Setup Mode, press SET for more than 2 seconds
while the meter is in Normal Mode.
Note...
To exit Setup Mode without saving, press ESC until Normal
Mode appears. If the meter is in Setup Mode, press ESC
twice to exit. For Conductivity, pH, and mV default settings,
refer to pages 70-71.
Memory Transmission
To transfer stored data from the meter to the computer:
1. Connect a RS232 or USB cable to the rear of the meter,
then connect the other end of the cable with the D-sub
connector to the computer’s serial port. Run the
15

on the middle of the LCD display and P1.0 appears
under “TR.”
3. Press . “OUT” flashes on the upper display and
P1.1 appears under “OUT.” This indicates that memories are transferring. After transmission, the LCD will
return to P1.0.
Note..
The meter can store up to 99 records for each parameter.
If you want to transmit data for a different parameter, press
