Functions
MODE key
By pressing the mode key, you can switch between the various measurement functions:
"MIN" Displays the lowest temperature value found during the measurement
"MAX" Displays the highest temperature value found during the measurement
"DIF" Shows the difference between the highest and the lowest temperature value
"AVG" Shows the average value
After the Testboy TV 325 has been turned off; the measured temperature values can be shown
®
again by pressing the MODE key. With each new measurement, the value of the old
measurement is overwritten and replaced with the new one. You can also use the MODE key to
set the alarm values for "high alarm" (HAL), "low alarm" (LAL) and emissivity (E). The Testboy
TV 325 changes the function with each press of the MODE key.
Use the MODE key to set the alarm values and emissivity as needed. Use the two arrow keys to
set the required value.
Lock function (continuous measurement)
The Testboy TV 325 can be turned to continuous measurement using the lock function. To
®
activate continuous measurement, press the "Up" key (arrow pointing upwards) on the operating
panel with the device switched on. You can see that the lock function is active as "Lock" is shown
in the display.
To disable continuous measurement, press the "Up" key again.
You can switch the laser and the background illumination on and off during continuous
measurement.
Targeting laser
When the laser is turned on, the laser point shows you the approximate middle of the measuring
surface. This makes more exact measurements possible. When the instrument is turned on, you
can activate the laser by pressing the "measure key" and the "down key". Hold until the laser
symbol appears in the LCD display. Now when you press the temperature measurement key, the
laser beam will point at the middle of the surface to be measured. In addition, the LED spotlight
provides additional illumination for poorly lit measurement objects. Press the "measure key" and
the "down key" again until the laser symbol disappears. This will turn off the laser.
