If a PIN code has been set, the user will be prompted to enter the code

when trying to access the menu. Entering the code correctly will disable

the lock until the user returns back to the basic view.

LOCK [x] [yyyy]

where

x = Keypad locking level, range 0...2. The options are:

0 - No lock (enables full access)

1 - Menu locked, but graphs are accessible

2 - Keypad completely disabled

yyyy = 4-digit PIN code. The code can only be set when keypad

locking level is 1.

Examples:

>lock 1 4444

Keyboard lock : 1 [4444]

>lock 1

Keyboard lock : 1

Data Recording

Data recording function is always on and collects data automatically into

the memory of the device. If the optional data logger module is installed,

the transmitter uses it automatically. Recorded data do not disappear

from the memory when the power is switched off. Collected data can be

observed in a form of a graph in the graphical view of the display or it

can be listed out by using the serial line or MI70 Link program.

Selecting Data Recording Quantities

If the device is provided with the optional display, the recorded quantities

are always those selected for the display. Up to three quantities can be

recorded at a time. For instructions on how to select the display quantities

with the keypad, see section Changing Quantities and Units on page 92.

DSEL

Use the serial line command DSEL to select the quantities to be recorded

if the transmitter is not equipped with display/keypad.
