5.3.5 Password Enable
There are two levels of password protection. The most restrictive level requires a password to do
instrument calibration. The second level requires a password to do SETUP functions.
If both password levels are turned off, no passwords are required, except in the VARS menu
where a password is always required. To enable password press SETUP-PASS-ON. A list of
passwords is in Table 5-5.

5.3.6 Time of Day Clock
The instrument has an internal time of day clock. The time of day can be set by pressing SETUP-
CLOCK-TIME and entering the time in 24hr format. In a similar manner the date can be entered
by pressing SETUP-CLOCK-DATE and entering the date in a DD-MM-YY format. If you are
having trouble with the clock running slow or fast, the speed of the clock can be adjusted by
selecting the CLOCK_ADJ variable in the SETUP-MORE-VARS menu (See Section 10.1.4).
5.3.7 Diagnostic Mode
The M100AH Diagnostic Mode allows additional tests and calibrations of the instrument. These
features are separate from the TEST functions because each DIAG function has the ability to
alter or disable the output of the instrument. While in DIAG mode no data is placed in the DAS
averages. Details on the use of Diagnostic mode are in Section 10.1.3.
5.3.8 Communications Menu
The COMM menu allows the RS-232 BAUD rate to be set. To set the BAUD rate press SETUP-
MORE-COMM-BAUD, select the appropriate BAUD rate, then press ENTR.
The instrument ID number can also be set. This ID number is attached to every RS-232 message
sent by the M100AH. To set the ID press SETUP-MORE-COMM-ID and enter a 4 digit number
from 0000-9999, then press ENTR.
