Use the System Setup to customize operation of your 2700 series meter. Press measurement screen and then press ENTER when SYSTEM is highlighted to access these settings.

The following settings can be customized for each model:

n

Stability

To aid with measurement and calibration, your meter has a unique feature that provides an

obvious visual indication when the reading becomes stable. If the Stability feature is enabled, the digits on the primary reading will be faded when unstable, becoming solid when stable. If this feature is disabled, the primary reading will always be solid.

n

Stability Criteria

The 2700 allows adjustment of the Stable indicator which relates to how fast and frequent it

appears. There are three levels of adjustment; SLOW, MEDIUM, & FAST.

To display a ‘Stable’ reading more quickly and more often, use “FAST” setting. MEDIUM or SLOW

is recommended for most applications. When Auto Read is enabled, a stability criteria setting of “SLOW” is recommended to for best results.

SLOW: The Stable indicator will take longer to appear and will appear less frequently. Use this

setting if you want the best results and don’t mind waiting longer to get them.

MEDIUM: This is the factory default setting. It provides a balanced response which works best for

most applications.

FAST: The Stable indicator will appear quickest of any setting. If you ﬁnd that the Stable indicator

frequently appears and disappears, you may want to select a slower setting. This setting is not recommended when AUTO READ is enabled. It is also not suitable for most non-reﬁllable electrodes which are generally slower to respond.

Auto Read

If AUTO READ is enabled, the measured value will automatically lock when the Stable

indicator appears. A ﬂashing “AR” icon conﬁrms this condition. To resume a live reading again, it is necessary to press MEAS each time Stable appears. Disable this feature to continuously view the active reading.

n

Backlight

Select “PERMANENTLY ON” on to keep the backlight on at all times that the meter is powered on.

This will oﬀer the best visibility but consumes the most power.

Select “ON WITH KEY PRESS” to turn on the backlight for a speciﬁed time after any key press.

Select “0” to keep the backlight oﬀ at all times that the meter is powered on.

n

Data Log (Storing Data To Internal Memory)

Select “SINGLE” to manually save one point at a time. Press the “MEM IN” function key any time

during measurement to save data.

Select “TIMED” to automatically save data at selectable intervals – ranging from 3 to 3600 seconds.

Data will be collected until the data limit is reached or until “SINGLE” data log is selected. This feature is useful for gathering data from a single sample over time. Note that “MEM IN” is not available during TIMED setting. As data is collected, the display will indicate how much memory has been used.

To view stored data, use “MEM OUT”. Note: the more data that has been acquired memory, the

longer the data will take to display.

n

Print Setup

Adjust the RS-232 output settings for baud rate, parity, data bit, and stop bit to match your printer

or computer settings as necessary.

n

Print Format

When utilizing the RS-232 output; choose “TEXT/PRINTER” option to send the data in an easily

viewable format – best for printing.

Choose “CYBERCOMM” option to send the data as a comma separated value (CSV) – best for

exporting data into spreadsheet software.

n

Print Set

This is identical to the Data log function, but data is sent via RS-232 output instead of

internal memory.

Select “SINGLE” to manually output one value at a time – best for printing or collecting data to

your PC from many samples.

Select “TIMED” to automatically output live data at selectable intervals – ranging from 3 to 3600

seconds. Data will be output until “SINGLE” Print set is selected. This feature is most useful for gathering data for use with software. Unlike the Data Log setting, data can be saved to memory using “MEM IN” during TIMED setting.

n

Date & Time

Setting the correct date and time is required for GLP and will apply to power oﬀ, measurement,

data log, and print functions. Instrument has battery backup to retain date/time settings upon power loss. Factory reset will not apply to date and time setting once it has been set. Changes related to daylight savings time must be manually entered.

Date Format : Select (MM DD YY) or (DD MM YY) Time Format : Select 12 Hrs (AM/PM) or 24 Hrs

n

Password

Select “ENABLE” to restrict access to Calibration and Setup modes. When password protection is

enabled, password entry is required before performing any calibration, or making changes to the setup mode. Setup parameters can be viewed, but can not be changed without correct password entry. The password is a user selectable number from 1 to 99999.

Select “DISABLE” if password protection is not desired.

The meter does not allow you to edit setup parameters or perform a new calibration unless you

enter the correct password. If an incorrect password is entered 3 consecutive times, the meter returns to measurement mode.

In the event the password can not be recovered, a password can be provided via a written request

to Eutech Instruments/Oakton Instruments. The instrument serial number and your contact information are required.

n

Clear Datalog

Select “YES” to delete all saved data that was manually or automatically stored into memory.

This step is most commonly required when the “TIMED” data log interval is not turned oﬀ and as a result, ﬁlls the memory to capacity. When the memory is full, deleting the saved data is required in order to save additional data. The 2700 will never erase old data in favor of new data when the memory is full.

If you wish to view, print or send the saved data to a PC before deleting, use the “MEM OUT”

function from measurement mode.
