Resetting the EVM
At times, you may need to reset the instrument if it is unresponsive.
1. To manually reset, press and hold On/Off/Esc for about 8–10 seconds and the instrument will
power off.
Lock/Secure Run and/or Setup
The lock or security feature is designed to lock the EVM during a run to ensure the session will not be
stopped unless the lock feature is disabled. Likewise, this feature includes a locked (or secure) setup
mode which will stop you from editing a set-up. Once one or both of these options are programmed with
a code, it is set by pressing the Lock soft key in the Setup menu.
NOTE: When securing or locking the instrument, it will be in lock mode even when powered off/on.
