e) Recording the measured value peaks (“REC”)
The “REC” function allows the highest and lowest measured values to be recorded and read out
from the device during measurement operation.
To enable the recording function “REC”, press the “REC” button (9).
The keystroke is signalled with a beep. The current measured value and the “REC” symbol
appear on the display. In the background, the lowest (MIN) and the highest (MAX) measured
values are automatically stored.
To read out the highest measured value on the display, press the “REC” button again. The
display shows “REC MAX” together with the highest stored value.
To read out the lowest measured value on the display, press the “REC” button again. The display
shows “REC MIN” together with the lowest stored value.
Pressing the “REC” button toggles between the MIN-MAX displays.
To start a new peak value measurement, you can use the “HOLD” button to delete the stored
MIN or MAX values. The display will then show “REC” and the peak value measurement will start
again for the selected function (MIN or MAX).
To disable the function, press and hold the “REC” button for approx. 2 seconds. The memory
function will be disabled with a beep. The measured values will thus be deleted.
f) Automatic shut-off feature
The meter will power off automatically after an operating time of approx. 10 minutes. This func-
tion saves battery power and extends the service life. The automatic shut-off function can be
disabled to allow longer measurements to be carried out.
Automatic shut-off can be enabled or disabled in the presets. For advanced presets,
see chapter 9 d).
g) Display backlight
The display is automatically backlit when the device is turned on to facilitate reading in poor
lighting conditions.
To turn off the backlight, briefly press the “POWER” button. The backlight will turn off with a
beep. To turn on the backlight, briefly press the “POWER” button again.
