VT02, VT04A, VT04 Users Manual High/Low Temperature Alarm (VT04A, VT04) High temperature and low temperature alarms are available on the VT04A and VT04. The temperature threshold is set for either the high or low alarm. When an alarm is set, you can quickly scan the scene and find objects that are above or below the threshold. An alarm condition is clearly shown on the screen as a flashing red/black band (High) or blue/black band (Low). See Figure 10.
Visual IR Thermometer Menu Functions Time-Lapse Image Capture (VT04A, VT04) The VT04A and VT04 have a time-lapse feature that monitors equipment with captured images at a user-set time interval. The user selects from a menu of preset values for both the time interval and duration. By default, the file name for these captured images includes an S, for example, XXXS.is2.
VT02, VT04A, VT04 Users Manual Auto-Monitor Alarm (VT04A, VT04) The Auto-Monitor Alarm feature is similar to the high/low temperature alarm feature. The difference is that instead of a flashing warning, the Product saves an image. When the temperature of an object in the scene goes above or below the threshold value, the Product saves the image. By default, the file name for these captured images includes an A, for example, XXXA.is2.
Visual IR Thermometer Menu Functions To prevent too many images being saved, there is a 10-minute delay between saved images. The delay applies only when a temperature threshold is breached and stays breached. When the scene temperature goes below (or above for low alarm) the threshold temperature, the delay is reset to zero. See Figure 11 for typical scenarios.
