pH Meter 713
8.713.1023 Enclosure for 8.713.1003 Instructions for Use
With series 13 and later, the 713 pH Meter is equipped with the new 5.713.0021 program.
The following pages list the most important modifications and extensions in comparison with
the old program version 5.713.0011 described in the 8.713.1003 Instructions for Use.
Modifications / Extensions
The format for the display and the entry of the date has been changed. The year can now be
entered with four digits.

>calibration parameters
cal.interval OFF h
Entry of a calibration interval
This inquiry appears only in the "pH" mode.
This new parameter allows the entry of a time
interval. When this time interval has expired the
warning "cal.interval expired" appears in the
LCD-display.
Input range: 1…999 h, OFF
The calibration interval is stored together with the
other calibration data for the electrode and the
electrode-id. The warning can be acknowledged by
pressing <quit>. When the electrode is recalibrated, the timer is set to zero. If no new calibration is performed, the instrument checks every
10 minutes whether the calibration interval has
expired, and again a warning appears in the display.
The verification of the calibration interval is always
carried out when the instrument is switched on or
when the mode is changed.
When further measurements are performed, although
the calibration interval has expired, together with
every measuring point report the warning
"calibration interval expired" is printed.

>calibration parameters
low lim.slope 0.97
Lower limit for slope
This inquiry appears only in the "pH" mode.
This new parameter allows the entry of a lower limit
value for the slope. If a smaller slope is found in the
calibration, the calibration can be discarded.
Input range: 0.001…9.999
>calibration parameters
up lim.slope 1.05
Upper limit for slope
This inquiry appears only in the "pH" mode.
This new parameter allows the entry of an upper limit
value for the slope. If a larger slope is found in the
calibration, the calibration can be discarded.
Input range: 0.001…9.999
>calibration parameters
low lim.pH(as) 6.40
Lower limit for asymmetry pH
This inquiry appears only in the "pH" mode.
This new parameter allows the entry of a lower limit
value for the asymmetry pH. If a smaller value is
found for "pH(as)" in the calibration, the calibration
can be discarded.
Input range: 0.000…99.999
>calibration parameters
up lim.pH(as) 8.00
Upper limit for asymmetry pH
This inquiry appears only in the "pH" mode.
This new parameter allows the entry of an upper limit
value for the asymmetry pH. If a larger value is found
for "pH(as)" in the calibration, the calibration can be
discarded.
Input range: 0.000…99.999
>electrode test
report: line
Report for electrode test
This inquiry appears only in the "pH" mode.
A new feature for this parameter is the selection of
"line". Only the result (e.g. "excellent electrode")
is outputted as a report for the electrode test.

req.ident: OFF
Automatic inquiry of the identification(s)
This new parameter allows the entry of samplespecific identifications before every measured value
printout initiated with <print>.
Id1 Automatic inquiry of the identification
"Id1".
Id1 & 2 Automatic inquiry of the identifications
"Id1" and "Id2".
OFF No automatic inquiry.

>plot parameters
New possibility of live plots
A plot function is now available for all those applications of the 713 pH Meter that feature continuos
measurement. The plot parameters depend on the
mode selected. They are shown here for pH mode.
You find additional plot parameter settings for the
<config> key (see p. 6) and for "setup" (see p. 7).

temperature on an external printer (with attached
temperature sensor).
