Analysis setup

User can set temperature alarm, alarm temperature, alarm color, isotherm color, isotherm temperature and isotherm width. Press Up and Down keys to choose menu items, Left and Right keys to modify the item contents. An alarm is triggered when a measurement cursor’s measurement meets or exceeds the Set Alarm Temp setting. All pixels above this temperature will change to the color as set in Alarm Color. When the Alarm Color is set to “None1”, the audible alarm will sound. When using alarms with Area measurements, the selected measurement mode, Min, Max or Average will have to meet or exceed the temperature in order to trigger the alarm.

  • Temp Alarm: OFF disables alarm function, ON enables alarm function and allows setting of Set Alarm Temp and Alarm Color.
  • Alarming Temp: Set the alarm detection temperature. Temp Alarm is set to on when it is enabled.
  • Alarming Color: Selects the color in which the alarming pixels are displayed. If set to “none”, no changes are made to the screen’s color. Temp Alarm is set to on when it is enabled.
  • Isotherm Color: Activates the Isotherm display by displaying the image in the set temperature range by the specified color. Setting to OFF, disables the feature.
  • Isotherm Temp: Set the center temperature of the isotherm.
  • Isotherm Width: Set the width of the displayed Isotherm band. For example, if Isotherm Temp is set to 122 °F (50 °C) and Isotherm Width is set to 1 °C, the isotherm band will be from 121.5 °F (49.5 °C) to 122.5 °F (50.5 °C).



Press the Menu key to activate the main menu. Select File->Open, press the Confirm key to open the saved images. Press Left and Right keys to change the images. Press C key to exit the opened image and return to measurement status. The image which is saved or opened at last will display first.

It is used for saving the image, performs the same functionality as the Save key. With Voice Save set in Save Settings menu, if Voice Save was On, Recording will start. Speak clearly into the microphone on the control panel. Record function allows up to 60 seconds of recording time and may be stopped at any time by pressing the Confirm key.

Save Setting:

Link Save – With Link Save “On”, the imager will save an IR image and a CCD image with every save operation. With Link Save “off”, the imager will only save whichever image the camera is viewing at the time of the save.

NOTE: When Imager is in the visible camera mode, thermal detector calibration does not occur and may result in lower accuracy images when saved. Always save the thermal images with thermal camera active, when Link Save is ON.

NOTE: To add voice comment to an already existing uncommented image, enable Voice Save, open the image to be modified and select File>Save. The imager will prompt you to record the message and the new image will be assigned to a new image number while the old image will remain unchanged.

Auto Save

Auto Save allows the camera to automatically save images at a 37 user-specified interval. Voice annotation is inactive with Auto Save. The function is disabled with auto Save is set to 0. To enable, select 10 to 3600 seconds (1 hour), in 1-second increments. Press the Confirm key, the recording timer will start saving images at the selected interval.


Delete is used for deleting the image. When camera is in image replay mode, press Menu key to activate the main menu, select File->Delete, press Confirm key to pop out the below prompt box. Press Confirm key to delete the current opened image. If it has voice comment, it will be deleted together. Press C key to cancel the deletion.

Battery safety and usage:

Batteries should be stored in an ambient temperature of -4°F (–20°C) to 67.9°F (+20°C). Lithium batteries will self-discharge during storage, so they should be fully charged before storage. Self-discharge may affect long term battery performance. Furthermore, it is recommended that the battery should be charged in a set time, as below;

Ambient temperature of:

-4°F (–20 °C) to 67.9 °F (+20 °C), once every 6 months

67.9 °F (+20 °C) to 113 °F (+45 °C), once every 3 months

113 °F (+45 °C) to 149 °F (+60 °C), once every month

Battery should have greater than 50 % charge prior to recharge. The ambient temperature for charging should be 32 °F (0 °C) to 104 °F (+40 °C). If under 32 °F (0 °C), the battery capacity will be diminished; if over 104 °F (+40 °C), the battery may overheat, resulting in permanent damage.

Battery Installation and Replacement

Inserting or removing battery

Battery compartment is located inside the handle. Turn the cover counter-clockwise to remove. Remove battery for replacement.
