GOOD LABORATORY PRACTICE

Good Laboratory Practice (GLP) is a set of functions that allows the

storage and retrieval of data regarding the status of the system.

After a successful calibration, the meter automatically stores the date

and time of calibration, the calibration solution used and the resulting

cell constant value. All such information can be recalled by the user.

To view last calibration data select the desired

range (EC or NaCl) and press the GLP key.

The first information appearing on the LCD

is the meter "id" code.

By repeatedly pressing the RANGE key, the GLP

data are displayed in the following order:

Last calibration date.

The following table lists the setup items, their valid range of values

and the factory settings (default):

Item Description Valid values Default

tc Temp. compensation coeff. 0.00 to 6.00 %/C 1.90

tcE Temp. compensation mode Atc, Mtc, notc Atc

tdS TDS factor 0.40 to 0.80 0.50

CEL Cell constant (K) 0.500 to 1.700 1.000

AoF Auto-Off enabled On, OFF OFF

YEA Year 1999 to 2098 1999

dAt Date (DD.MM) 01.01 to 31.12 01.01

hou Time (hh.mm) 00.00 to 23.59 00.00

id Meter identification code 0000 to 9999 0000

vEr Firmware release

Notes:

I Once enabled, the Auto-Off time is fixed at 5 minutes.

II Assigning an ID code is helpful in identifying a particular meter

from others.
