|
| Sequential Function Routine |
This instrument is provided with 50 steps which can be
utilized to make up one or more programs
Each program can consist of a number of soak and ramp simulations measurements and standby steps. |
| Low battery test |
|
|
| A test is provided at 3 different levels: |
|
- Level 1: the instrument is fully operative
- Level 2: the instrument shows the message
“BATTERY LOW” on the upper display while
the lower display shows the measured or
generated value.
The instrument is still fully operative.
- Level 3: the instrument turns OFF
automatically and utilizes the remaining
power for memory back up only.

| Logic
Inputs |
The MEMOCAL 2000 is equipped with 2 logic inputs.
They are mutually exclusive with serial interface.
These 2 logic inputs have the following functions: |
- Logic input 1: sequences to the next program step.
- Logic input 2: it allows to start or to suspend the program execution (RUN/WAIT)
|
