1. Introduction
We thank you for having purchased PL-600 lab pH meter。
Before using the instrument, please note that the operation
instructions should be read carefully, which will help you to operate and
maintain the instrument, as well as to avoid trouble caused by unsuitable
operation and maintenance.
PL-600 pH meter employs leading edge technology with integrated
microprocessor, which is suitable for pH and mV measurement in water
solutions for institutes, industrial labs and production fields.
The information presented in this manual is subject to change without
notice as improvements are made.

Icon ①：RS232 communication
strument has been connected with PC, When this icon displays, the in
the PS232 communication function is open automatically.
Icon ②：Timing storage of the measurement value
（only valid for type
640） When this icon displays, the measurement value timing storage
function is open, the instrument will store the measurement data according
to set intervals.
Icon ③：Sensor diagnostics
、 、
After pH sensor calibration, the instrument will display sensor
performance：
：sensor is in good performance；
Icon④：Measurement status icon
：sensor performance is so so；
：sensor is in bad performance, need to be changed
、 ：
：when display this icon, the measurement value is in stable status,
but the instrument still goes on measurement.
：when display this icon，the measurement value is in stable
poising status, the value will be kept(auto ending point
function)
