1. DESCRIPTION
The Comark N3000 Diligence EVG Graphics Monitor range of new instruments is designed to meet all your data recording needs. These monitors take data recording to another level with the introduction of a large backlit LCD for a clear view of the data in both list (tabular) and graph mode.
Paper and pen chart-recording of data will become a thing of the past with Diligence EVG Monitors. The N3000 range combines all the features associated with the successful Comark Diligence EV data loggers and adds additional features never seen before on a Comark instrument.
Comark Diligence EVG Graphics Monitors have been designed for applications throughout industry and processing, including the food industry
and scientic and research laboratories.
Each Diligence EVG Graphics Monitor has a very large memory (up to 64,000 readings) for the most demanding applications and can be used with the existing range of Comark temperature probes.
The stored data points can be displayed directly on the large LCD display or sent to a PC or to a printer.
The large LCD display is used to indicate all programming and set up, as well as for the display of valuable information on the status of the instrument and the measurement channels. Throughout this manual the various presentations of information on the LCD are referred to as “screens”. This also differentiates the LCD presentations from the software presentations, referred to as “pages”.
The proven Evolution software provides for the programming of Diligence EVG Monitors and enables the stored data to be saved on a PC and displayed in list or graphical form.
The rst instrument in the N3000 range is the N3014 detailed in this
manual.

2. OVERVIEW OF EVOLUTION GRAPHIC MONITORING
The N3014 stores readings at pre-set intervals for all active channels in its large memory. Each reading stored is time and date stamped. The interval time is programmable from 1 second to 99 hours. There are a number of user programmable options including alarm intervals, sensor type, channel set-up, and start/stop times. These options are detailed elsewhere in this manual. There are also options available for setting the times for data recording. These include:
Manual start/stop Manual start/timer stop Timer start/stop Wraparound (continuous logging) Daily logging.
Manual start/stop. The N3014 will only start to record data and stop recording when manually instructed from the keypad.
Manual start/timer stop. The N3014 will only start logging when manually instructed from the keypad. The pre-programmed stop time will be automatic.
Timer start/stop. The pre-programmed start and stop times will be automatic.
6
Wraparound recording. Data will be recorded until the N3014 memory is full and new data will be written over the oldest data in the memory.
Whenever the N3014 starts a new logging cycle after a time during which no logging has taken place, a new section is created within the data. Each
separate logging section is therefore related to a specic logging time
period and is referred to as a period. The N3014 can store a maximum of 128 periods.
Data can be displayed in real time on the large graphic LCD while also being stored in the internal memory for later transfer to a printer or upload to a PC for storage, and analysis.
3. OVERVIEW OF KEYPAD SYMBOLS
The keypad has a number of buttons for the operation of the instrument and a number of LEDs for active indication of events. The button functions are:
ON/OFF – Use this button to power the EVG display on and off to save power. The instrument will not stop logging or lose data if the display is turned off.

7. CONNECTING PROBES TO THE INSTRUMENT
The rst N3000 instrument is the N3014. This is an eight-channel thermocouple monitor tted with industry standard sub-miniature
connectors.
When connecting probes, the polarity of the plug must be checked before
tting. N.B. In order to obtain correct results make sure that the correct
thermocouple type for the probe in use has been selected.
Comark type K thermocouple probes have a Green (Red in USA) lead and
type T themocouple probes have a Brown (Blue in USA) lead.
Note: It is recommended that insulated thermocouples are used with the N3014 eight channel instrument.
8. SWITCHING ON AND OFF
8.1 Display Test/Mode
The logging function is available as long as power is supplied to the instrument, from batteries or mains, but the large LCD can be switched off using the ON/OFF button. Whenever the display is turned on it will perform a self-test during which time the Comark logo will be displayed. After the self-test is completed, The LCD will return to the previously displayed screen or the home screen as appropriate.
9. PROGRAMMING THE INSTRUMENT
The instrument can be programmed in two different ways. Firstly, it has been designed to be compatible with the existing Evolution software for programming via a PC. Secondly, it can be programmed via the keypad. The next section ‘Using the Evolution Software’ will deal with programming via the software and the following chapter ‘Manual Setup for EVG’ will cover the setting up the instrument without software or a PC.
10
10. USING THE EVOLUTION SOFTWARE
The N3000 range of monitors can be used with N1SW version 3.1 or above, however EV or EVSWPRO is recommended. If required, software
upgrades can be obtained from the Comark Sales Ofce or a local Comark
distributor.
Note: Before attempting to install the software please read the software installation guide supplied with the software.
10.1 Writing a Task for the EVG
Note: It is recommended that this part of the manual be read while referring to an instrument connected to a PC.
With the software installed and preferences set (see software installation guide) the system is ready for a task to be written. All
programming of Evolution models is via TASKS. In this way the
task may be saved as a record of the program given to the monitor and as such may also be retrieved for later use. Connect the EVG
monitor to the PC via the cable supplied. This will t only the 9-Pin
RS232 connector on the side of the EVG. From the Evolution software select Quick Program from the Shortcuts menu. After a few seconds the Static Task screen will be displayed on the LCD of the instrument.
10.1.1 Channel Setup
The number of channels available will be shown across the screen as a series of ‘TABS’. To set up a particular channel click on the relevant TAB.
Each tab will allow the conguration of a number of options
pertaining to that channel. The display will show a tick box
to turn the channel on and off and a description eld for the specic channel, which will be displayed on the EVG LCD.
Settings also include the sensor type, if applicable, individual
High and Low alarms for each channel, and nally the alarm
time delay. For example an alarm time delay can be set to cover defrost cycles e.g. A delay can be set between 0-99 seconds or minutes.
11
Note: Alarms will be triggered if the measured value rises above, or drops below, the entered Hi and Lo limits.
The rest of the settings are not specic to any N3000 model.
10.1.2 Recording Setup
The 'logging' section of the Task allows programming of the interval time 1-99 seconds, minutes or hours, manual start/
stop reording, specic date/time recording with or without a
manual start and daily recording between two times. Daily
recording can be over midnight and set for specic day or days
of the week.
If manual start/stop is selected, the option start or stop is presented on the home screen of the instrument display.
10.1.3 Miscellaneous
The miscellaneous settings will allow for setting up of the alarms, turn on or off, setting latched alarms and turning the bleeper on and off. Memory wraparound (continuous logging) is also enabled from here.
10.2 User Details
The User details screen allows the programming of 12 text elds, headed title and description. The title eld can be up to 16 characters while the description eld can be up to 24 characters. Finish with OK or Cancel to abort.
10.2.1 Instrument Clock
The instrument date/time can be set either to synchronise with the PC clock or manually. The manual setting is useful if the clock in the instrument is to be set to a different time from the PC clock, e.g. set to GMT Greenwich Mean Time when the local time differs, i.e. BST British Summer Time. Note: The instrument timeclock will not adjust for BST.
12
10.2.2 Password Protect
Use the Password protect elds to enter an alphanumeric
password of up to four characters to protect programming or data retrieval, or both. Only one password can be set and this protects both programming and data retrieval. More options are available via manual programming, see section 13.1.
10.3 Saving the Task
The task is now complete and can be saved for later reference by using the ‘Save Task’ button. This will display a standard File-Save-
As Window. From here a lename can be entered for the task and
saved on the PC.
10.4 Program Task
Progamming tasks is made simple by the ‘Program-Now’ button. Press this button with the instrument switched on and connected to the PC and the software will send the new Task information to the instrument. If the instrument is password protected then the password will have to be unlocked, see Unlock Password below. Once programmed the instrument monitor is ready to go. If the instrument has been programmed for manual start, this option will appear on the home screen. If the instrument has been programmed for daily or dated recording then it will start recording automatically and requires no further input.
10.4.1 Unlock Password
From the menus at the top of the screen, select File-Unlock Password. Enter the password to unlock the instrument for programming or data download.
Note: If the password programmed into the instrument is forgotten, the instrument will have to be returned to Comark Ltd.

10.5 Retrieving Data
Once the logger has completed the task, the data can be downloaded for viewing. Connect the instrument to the PC with the ADP53 N3000 Comms Lead and select the Retrieve Data shortcut. The software will scan the instrument for data and will ask for a
lename for the data le. If the logger is password protected and the
password has not been unlocked then the data cannot be retrieved. See Unlock Password above.
At this point the software will ask for a lename for the data. It will
then ask if the memory is to be cleared and if the instrument is to be returned to ‘non-logging’ basic mode. Once these questions have been answered the data will be displayed on the screen. It is now possible to print and graph the data.
10.6 Data Manipulation
10.6.1 Graphing, Printing and Data Export
The data will be displayed in list mode but can be graphed or printed at the touch of a button. The quickest way to print or
graph the whole le is to select the ALL tab and then select
either Print Current Tab or Graph Current Tab. Additionally a portion of the data can be highlighted by using the mouse. This selection can then be copied and pasted on to a blank graph. (A new graph Window is created by selecting File-New­Evolution Graph). Additionally the data can be also pasted into a Word Document or Excel Spreadsheet.
10.6.2 Quick Calcs
The Quick Calcs function will calculate the following values from the selected data: mean, minimum, maximum, standard deviation and elapsed time. These calculations will only apply to data previously selected using the mouse. Select the whole or part of the data and press Quick Calcs to view the results. N.B.

18. CARE OF THE INSTRUMENT
Use a damp cloth to remove dusty deposits. Use a mild soapy solution to remove hard or sticky deposits. Do not use solvent-based cleaners or methylated spirit, etc. The instrument is not waterproof.
Only use the power supply/battery charger supplied.

19. CHANGING THE BATTERIES
The instrument is tted with 4 rechargeable AA Ni-Mh cells and these
should last many years before replacement is required. In the event that
these go at or where a mains supply is not available, standard alkaline cells can be tted. When the battery needs changing the Low Battery LED will ash. At this point, either connect the power adaptor to recharge the
batteries or replace the alkaline cells. To replace the batteries, slide off the battery compartment cover and replace all four cells. Never mix new and old cells and do not under any circumstances mix rechargeable cells with non-rechargeable ones. Be careful to observe the correct polarity.
The switch in the battery compartment must be used to select rechargeable or normal batteries.
Note: If a low battery warning is indicated at switch-on, replace or recharge batteries immediately to continue to use the instrument. To avoid losing date and time, batteries must be replaced as soon as possible. The data in the instrument is always protected.
Battery charging starts from the moment external power is supplied. It takes about 48 hours to fully charge the supplied batteries. This is indicated via the yellow LED. If the external power is removed and replaced within 4 minutes the charge timer will not restart.
Once charging is completed the batteries will be trickle charged.
