Locking the Instrument
The 38DL PLUS offers an instrument lock allowing a supervisor to restrict access to
selected functions. The supervisor can also enter a password to prevent other users
from unlocking the functions. Once a password has been set, you must reenter the
password before you can lock or unlock any function.
You can lock the following functions:
•
Calibration with [CAL VEL] and [CAL ZERO] ([2nd F], [CAL ZERO] (Do ZERO)
still available)
•
Setup menus accessed with [SETUP MENU] and [SP MENU]
•
Transducer setup recall with [XDCR RECALL]
•
Datalogger operations (except [SAVE/SEND])
•
Gain adjustment with [GAIN]
•
Waveform adjustment with [WAVE ADJ]
Locking the calibration prevents changes to calibration values so that no parameters
can affect the value of the measurement; these include material velocity and test block
zero calibration. However, you can still view these values, use the measurement
screen, and use the datalogger functions.
Anytime a user attempts to use a locked function, a message appears in the help bar to
indicate that the function is locked (see Figure 8-8 on page 124).
