Keypad lock
To prevent manipulation during ongoing monitoring, it can be advantageous to activate the key lock. This
function can be found in the main menu under “Key Lock”.
When the key lock has been activated and you left the menu, you may only retrieve information using the
keys F1 and F2.
To release the key lock, press all four arrow keys simultaneously until the instru
ment displays “unlocked”.
Alternatively, the key lock can be switched on and off by a command sent via the USB interface.
Adjusting the axes
The PCE-VM 40 contains a tilt sensor for adjusting and monitoring the vertical alignment. The menu item
for axes adjustment is located in the main
menu under “Device settings”. Here, you will see a graph which
resembles a spirit level. The moving point has to be located within the circle. If this is the case,
“OK” will
be displayed on the left of the screen.
To install/mount the PCE-VM 40 on various floors or surfaces in conformity with a standard, PCE
Instruments offers a tripod floor plate with adjustable feet.
The axis adjustment is monitored during measurement operation. If the axes have been adjusted
incorrectly, the flashing warning “Adjust Axes!” will appear in place of the standard.
