4.5 System Operations
Model TH1942 has some other operations: Beeper control, key sound control, Baud rate control and
Terminal character setup. The information is not directly related to making measurements but is an
important part of operating the multimeter.
4.5.1 Beeper Control
Normally, the multimeter will emit a tone whenever certain conditions are met. For example: the
multimeter will beep when a stable reading is captured in reading hold. You may want to disable the
beeper for certain applications.
When you disable the beeper, the multimeter will not emit a tone when:
1. A limit is exceeded in a limit test
2. A stable reading is captured in reading hold.
Disabling the beeper has no effect on the tone generated when:
1. An internal error is generated.
2. The continuity threshold is exceeded.
3. A front panel key is pressed.
The beeper state is stored in non-volatile memory and does not change when power has been off
or after a reset. The beeper is enabled when the multimeter is shipped from the factory.
Use the following steps to change the b
eeper‘s state:
1. Press
Shift
→
to enter the menu on the menu level,
―
A: MATH MEU

will be displayed.
2. Use

3. Press
to move down to the command level within the SYS MEU.
4. Use

7. Press
(ENTER) to confirm the beeper control. The message
―SAVED
”
will be displayed to
show that the change is now in effect. TH1942 will exit the parameter level and move up a level to
the command level.
8. Press
Shift
→
key to exit from the menu and return to the measurement status.
4.5.2 Baud rate
