MAIN MENU SCREEN
This screen provides access to the menuing system, through which you set
up your instrument and choose the desired test parameters. Navigation of this
menuing system is by means of the cursor control and Enter key.
At the top of the screen are the three main menu choices; “
TEST
”,
“
OPTIONS
” and “
CURRENT
”.
Below this are details of the test current selected (
SET CURRENT
),
maximum current to be allowed (
CURRENT LIMIT
), the number of stored
tests and the current date and time.
To perform a measurement is straightforward.
1. Use the Left and Right arrows of the two-axis cursor control to
highlight the
TEST
menu. Use the down arrow to select the
required test type. Press Enter.
2. Use the Left and Right arrows of the two-axis cursor control to
highlight the
CURRENT
menu. Use the down arrow to select SET
and press Enter. Type in the desired current using the numeric keys
on the keypad. When finished press Enter.
If the current you have set is greater than the current limit, DLRO200
will beep and clear the
SET CURRENT
field. Re-enter the desired
current, if necessary increasing the current limit to a value equal to
or greater than the desired level. (See separate topic for setting the
current limit).
3. Connect the sample to be tested to the instrument terminals and
press the
TEST
button. The different test types have slightly
different connection requirements, which are detailed, in the
sections below.
