1. Using the SQ1600 controls
Your SQ1600 can be PC based but is also is a self contained data logger in its own right with a built in
control panel and LCD screen for local monitoring of reading, configuration of the data logger and down load
capability.
You can control the SQ1600 using the display and buttons on its top cover:
The display is a 20 character, two-line LCD. During normal operation the display will be blank and unlit to
conserve power. Whenever a button is pressed a menu or message will be displayed and the backlight will
operate for ten seconds.
There are two pairs of buttons, one pair to move the cursor within a screen and one to navigate through
screens.
To move the cursor, use the two arrow buttons:
Clicking these buttons will select either the previous or the next option within the screen currently shown on
the SQ1600 display.
To navigate through screens use the Esc and Enter buttons:
The Esc button will close the current screen and move to the previous screen within the hierarchy. Pressing
this button repeatedly will display the Home screen. The Enter button will select the currently highlighted
option on the screen.

2. SQ1600 screens
You can access SQ1600 functions from the Home screen, which contains a number of options:
•Meter
•Log
•Alarms
•Status
•Config
•Off.
Meter
Selecting this option will show any currently operating sensors and their readings. If you hold the Enter
button, the sensors will be shown in sequence. When you release the Enter button, the displayed sensor will
remain selected.
Log
This option allows you to start, pause or stop a logging run. The current status is shown in the bottom right-
hand corner of the display, with the available options on the top row.
Alarms
This option shows the current status of any alarms that have been set up. If you hold the Enter button, the
alarms will be shown in sequence. When you release the Enter button, the displayed alarm will remain
selected.
Status
This option allows you to view operational status details for the logger. A further screen is displayed in which
you can select:
•Logger Text, which displays the text defined for the logger during setup
•Run Text, which displays the text defined for the current run during setup
•Memory, which shows the memory used for the current run (Internal or either of the two optional PC
cards)
•Supply, which displays a menu allowing you to select Backup, Internal or External; selecting an
option shows the voltage level of the selected supply
•Runs, which shows a list of current runs; selecting a run shows its run text, and holding the Enter
button will delete the run from the logger
•Copy, which allows runs to be copied but is only displayed if logging is not in progress, the PC card
option is fitted and there is a card present in at least one of the slots; the source and destination of the
copy are determined automatically from the presence or absence of cards in the two PC card slots: if
card 1 (upper slot) is inserted it will be the source of any copy; if card 2 (lower slot) is inserted it will
be the destination of any copy; in this way it is possible to do all varieties of copy; hold the Enter
button to copy the run selected by use of the arrow buttons
•Version, which displays a menu allowing you to select Digital or Analogue; selecting an option
displays for Digital the logger model and firmware version information, and for Analogue the date
and time of calibration and firmware version information.

Config
This option allows you to view configuration details for the SQ1600. This will display a screen containing the
following options:
•Time, which shows the current date and time for the logger
•Memory, which allows you to specify the memory to be used for logging; the current selection is
shown in the bottom right hand corner
•Language, which allows you to change the language used for logger displays to German, French,
Italian or Spanish; the default language is English
•Battery, which allows you to specify the type of battery used (Alkaline or Lead-Acid); the current
selection is shown in the bottom right-hand corner; you can select a type using the arrow buttons and
then hold the Enter button; note that the logger is able to determine the type of battery fitted
automatically hence this function should only be used to change the type if you are certain that the
automatic selection is incorrect
•Setup, which allows you to select one of five setup configurations for the logger; highlighting a setup
will show its logger text (the message Invalid Setup will be displayed if the setup has not been
configured); make your selection using the arrow buttons then hold the Enter button to load the
setup.
Off
This will turn the SQ1600 off. You can then restart the logger by clicking any of the buttons or starting
communication using the serial port.

3. Checking logger operation
The SQ 1600 data logger is supplied with an integral setup program that allows you to confirm that it is
operating correctly. To perform this check:
1. Plug the K-type thermocouple wire plug supplied with the SQ 1600 into input A of the SQ1600.
2. From the SQ1600 Home screen, select the Config option to display the Configuration menu.
3. From the Configuration menu, select Setup to display the Load Setup screen:
4. Position the cursor over the number 1 then press and hold the Enter button as the preset program loads.
5. When the message Finished Loading is displayed, release the Enter button.
6. Press the Esc button twice to display the Home screen, and select Meter. The display will show channel 1
and should indicate a value of approximately room temperature.
7. Hold the end of the end of the thermocouple wire between your fingers. The indicated temperature will
increase if the SQ 1600 is functioning correctly.
