All functions on the transmitter are completed using the two buttons on the front of the transmitter. The WiFi Button has several functions: Press and hold for one second. The connection to the WiFi could take up to a minute from the button press.
Page 14
Over Range and Under Range warnings will be displayed when the reading is greater than or less than the max that the display show i.e. >19999 or <-19999. When the maximum measurement value is exceeded i.e. is >32000 or <-32000 then the display will show four dashes.
After exiting Setup Mode the transmitter should be provoked by pressing the WiFi Button until the Activity LED (Green) activates. This will start a WiFi session with the Diligence Cloud. If all is well the WiFi Signal icon ( ) will remain solid. This may take a few seconds in order for a connection to be established.
Page 16
Transmitters are nested under two different sub-headings, on the Diligence Cloud data management platform, which are Locations and Alarm Groups. This is to provide a suitable context for each transmitter, in your estate of devices, that relates to its physical location. Transmitters are nested within Alarm Groups and Alarm Groups in turn are nested within Locations.
Page 17
New Locations and Alarm Groups are added via the Diligence Cloud data management platform. • Adding a New Location From the Diligence Cloud homepage click on the menu icon top-left and navigate to Locations. Next, click on the Create Location icon and enter the name of the Location in the field provided.

Tasking is a defined set of instructions (Task) sent to a Diligence 600 transmitter to ensure that it records temperature and other data at the frequency required and to ensure that alerts and alarms are also sent as required. The Task defines all the criteria required for the transmitter to operate. All mandated elements of the Task must be entered correctly to ensure correct operation of the transmitter.
Page 20
• Log Rate Each Task must include a Log Rate for the transmitter in order to log data regularly. This must be in the range 1-60 minutes. There are pre-set Log Rate values of 1, 2, 3, 5, 10, 15, 20, 30 and 60 minutes.
Page 21
At least one channel can be activated for data logging per transmitter. Therefore, at least one channel is mandated for selection before a Task can be considered valid. • Internal (Integral) Channel If applicable, the Internal (Integral) Channel can be selected. This channel is either integral or, in the case of Thermocouple variants, is available once a Lumberg probe is connected.
Page 22
The Diligence 600 WiFi Monitoring System will alarm in several different ways and, depending on the licence applied to the Diligence Cloud platform, there are two types of Temperature Alarm for Diligence 600 transmitters. High and Low Alarms are traditional alarms which will generate the alerts/emails from the Diligence Cloud.
Page 23
An alarm will be triggered when the temperature, or other parameter, exceeds the programmed alarm value, by a value equivalent to the minimum resolution. For example, given a High Alarm of 8.0°C on a Diligence 600 WiFi Temperature Transmitter (RF612), an alarm will be triggered for any reading that is recorded at 8.1°C or above.
Page 24
When the temperature goes out-of-limit, extra records are logged as indicated by the blue dots as follows: The record logged as the temperature goes out-of-limit (high) The record logged because the temperature has remained out-of-limit throughout the alarm delay The maximum temperature reached for the out-of-limit period The record logged as the temperature again becomes within limits The record logged as the temperature goes out-of-limit (low) The minimum temperature reached for the out-of-limit period...
Page 25
There are two types of Door Sensor Alarm: Continuous Door Open • Average Door Open • Here a duration between 0 and 60 minutes can be set for a Continuous Door Open alarm. If the door remains open for the set duration then the alarm is triggered. For this alarm type, two parameters need to be set.
Page 26
A Door Sensor Alarm is indicated by a flashing Door Sensor Alert icon ( ) , as well as a flashing Alarm LED (Red). Use the Action Button to scroll through to Channel 5, where the current Door Open Average Period is shown.
Page 27
Diligence 600 transmitters only have a single Logging Mode, although there is the added option of setting logging to a Manual Start. During logging the transmitter will complete the following actions: Under normal circumstances a transmitter will automatically start logging as soon as it receives a Task from the Diligence Cloud.
Page 28
If a transmitter is experiencing difficulties connecting to the Diligence Cloud, then please check the following: Ensure that a WiFi Protected Access Pre-Shared Key (WPA-PSK) network is available. This type of WiFi network usually requires a password to gain access. Ensure that the right WiFi (WPA-PSK) password is being used.

After another five seconds the display will change and show a negative value. The value displayed provides an indication of the signal strength in dB. This value will always be a negative value. • -59dB and above = Excellent signal (four bands of WiFi Signal icon ( -60dB to -79dB = Good signal (three bands of WiFi Signal icon ( •...
Page 30
Here are some common checks to perform, should the transmitter not connect to the required WiFi network: Check that the correct (WPA-PSK) password is being entered. Check to see if 802.11b is enabled on the router, access point or signal repeater and consider switching if off.
Page 31
Diligence 600 transmitters can swap between WiFi access points while still tasked and logging data to the Diligence Cloud. NOTE –The transmitter will stop logging data for the duration of the process. To change the access point to which the transmitter is connected, simply follow the instructions for setting up the transmitter in the Quick Start Guide (QSG) supplied with the transmitter.
Page 32
If the transmitter wakes up to send its data or to alarm, but is unable to do so, then the transmitter will attempt further connections in the following sequence: • Once per minute for the following three minutes • Then once every five minutes for the next fifteen minutes •...

Battery Replacement is straightforward. If wall-mounted, remove the transmitter from the mounting bracket then disconnect any external power supply unit (PSU). Using a screwdriver, fitted with a small flat or Pozidriv head, remove all four screws from the rear battery compartment. The screws should remain captive in the cover. Remove the cover.
Page 34
Restarting a Diligence 600 transmitter should not be necessary under normal operation. However, if a transmitter is having trouble connecting or any problems are experienced whilst setting up the transmitter, then the transmitter can be restarted by removing one of the battery cells from the battery compartment for at least ten seconds then re-fitting the battery cell and securely replacing the battery cover.
Page 35
There are several on-screen messages that are displayed on the transmitter, depending on the current status of the transmitter. These are explained as follows: The transmitter is in a low power sleep state, as when newly supplied. To activate the transmitter simply press the Action Button.
Page 36
The WiFi Signal icon ( ) will animate to show signal is being sent. Search for available wireless networks on your internet enabled device. The Service Set Identifier (SSID) or Network Name of the transmitter will be shown. This is the same as its Serial Number, which is printed on the rear label of each Diligence 600 transmitter.

What type of WiFi do I need? Comark Diligence 600 WiFi transmitters require WPA2-PSK WiFi access, which is similar to that of a domestic WiFi network which generally only requires a password for access. Should the WiFi network not have this type of security, then please refer to the relevant IT department...
Page 55
What is self-heating? Radio rates of less than five minutes can cause internal self-heating of the transmitter, which will result in a slight heating effect on the integral sensor. This can result in the internal temperature sensor recording ambient temperatures approximately 1°C greater than actual. We therefore recommend that the integral sensor be switched off if the transmitter is required to operate with a radio rate of less than five minutes.
