This button has two functions:
1) When pressing this button for a long time, the system switches between Search and
Measuring Mode. For this, the button is pressed until the red “STATUS” LED is turned off again.
Before switching over, the instrument performs a Zero setting so that there will be a short delay.
2) IN THE MEASURING MODE ONLY: Pressing this button briefly will expand the display range
of the analogue pointer gauge of the handset. Pressing this button once will select factor 1 set up in the user
setup (green “SPECIAL” LED flashes slowly). Pressing this button once more selects factor 2 (green
“SPECIAL” LED flashes rapidly). When pressing this button once more briefly, or pressing the Zero button,
the
SF6 LEAKCHECK P1:P will switch back again to the normal display mode.
Setting of the measured value to Zero. For a brief moment the LED indicator will change from
“READY “ to “NOT READY”. Since during this time and if necessary the energy flow to the
sensor is corrected, the Zero button should be in any case operated from time to time even if no
deviation from the Zero level is present.
When the extended display range is active, it will also be disabled.
IN THE MEASURING MODE ONLY: The peak value indicated on at the bottom on the right of
the screen is saved and thereafter set to Zero. Saved values may later be output through the
serial interface to a computer or printer. Pressing this button for a long time, displays the option
“Data Memory Control” serving the purpose of administrating saved measured values.
