P7.0: Conductivity or TDS Measurement Configuration 

P7.1: READY indicator and auto endpoint function 

This program lets you select: 

READY indicator on

” to indicate when the reading

is stable.

READY indicator off

” for faster meter response.

Auto endpoint function on

. Select auto endpoint on

to “hold” the reading when it is stable for more than 5

seconds. The display automatically freezes, and the

HOLD indicator appears on the left side of the

display. Press the HOLD key to release the display

and access other functions.

From measurement mode 

1.

Press 

the 

MODE

 key to select conductivity or TDS

measurement mode.

2.

Press 

SETUP

 key to enter Set Up mode.

3.

Press 

the 

 

or

 

 keys to scroll through subgroups

until you view parameter P7.0.

4.

Press 

ENTER

 key to select parameter 7.1.

5.

Press 

the 

 

or

 

 keys to select the configuration

you require.

OFF switches the READY indicator off;

ON switches the READY indicator on.

ON and HOLD together switches the auto

endpoint feature on.

6.

Press 

ENTER

 key to confirm selection and to

proceed to step 4 of P7.2.  You can also press the

CAL/MEAS

 key to return back to measurement

mode.

NOTE

: Meter default is set for Ready Indicator on, and auto endpoint function off.
