OPERATING INSTRUCTIONS Upon start-up, the instrument shows the following 6 operating modes, which can be selected through the arrow keys S or T, confirming with ENTER IR VIDEO IR MEASURE DEW POINT DATALOGGER DATA MEMORY SETTINGS Fig. 25: Instrument general menu MEASURING MODE DESCRIPTION IR VIDEO IR temperature measurement with in-built photo camera + IR video recording + relative air temperature/humidity measurement with internal sensor (see § 7.
HT3320 7.3. IR VIDEO MODE This mode allows carrying out IR temperature measurement with the in-built photo camera, saving the images in standard JPG format, recording IR videos of IR temperature measurements saving them in 3GP format, measuring the air temperature/humidity with the in-built sensor and measuring temperature with type K probe (if enabled – see § 6.10) 1. Switch on the instrument and enter the “VIDEO IR” mode 2. Set the desired values of the measurement parameters (see § 6) 3.
HT3320 8. Make sure that the object whose temperature is to be measured is at least as large as the unit’s spot (see Fig. 28). The smaller the object is, the closer you should be to it. When accuracy is critical, make sure the object is at least twice as large as the spot size. To find a hot spot, aim the thermometer at the measured object, then move the instrument across the object until a hot spot is located. Fig. 28: Spot size area 9.
HT3320 7.4. INFRARED TEMPERATURE MEASUREMENT This mode allows rapidly measuring the IR temperature without using the in-built photo camera, further to carrying out air temperature/humidity/dew point/wet bulb measurements without saving them in the instrument’s memory. 1. 2. 3. 4. Switch on the instrument and enter the “IR MEASUREMENT” mode Set the desired values of the measurement parameters (see § 6) Hold the meter and point it towards the object whose temperature is to be measured.
HT3320 7.5. DEW POINT TEMPERATURE MEASUREMENT This mode allows displaying the dew point temperature, which is useful when making thermographic surveys for the construction sector, further to the normal IR temperature measures and air temperature/humidity measures. 1. 2. 3. 4. Switch on the instrument and enter the “DEW POINT” mode Set the desired values of the measurement parameters (see § 6) Hold the meter and point it towards the object whose temperature is to be measured.
HT3320 7.6. DATALOGGER FUNCTION In this mode, the instrument records the IR temperature and air temperature/humidity values with time scan and programmable alarm conditions on the measures. 1. Switch on the instrument and enter the “DATALOGGER” mode. 2. Set the desired values of the measurement parameters (see § 6) 3. Press the ENTER key to enter the programming section of the datalogger function. The following screen appears on the instrument’s display: Fig. 31: Datalogger function parameter setting 4.
HT3320 7.7. TEMPERATURE MEASUREMENT WITH K-TYPE PROBE WARNING • • Do not compare the infrared temperature measurement with the measurements made with K-type thermocouples, since (because of the totally different nature of the two methods) the obtained values may differ remarkably Measurement with the K-type thermocouple can be used in situations where IR measurement cannot be used (e.g.: measurement of shiny/bright surfaces such as glass and plexiglas) 1.
HT3320 8. OPERATIONS WITH THE MEMORY The instrument allows saving, in the internal memory or in the external mini SD Card (see § 5.10), IR images in JPG format (640x480pxl), IR videos in 3GP format and recordings in BIN/TXT format. These data can be recalled on the display as follows: 1. Select item “DATA MEMORY” using the arrow keys S or T and press ENTER. The following screen appears on the instrument’s display: Fig.
