Key assignments

Eight keys are available for operating the ULTRAMAT 23. These keys have the following
meanings:
No. Designation Description
1* MEAS Measure
2 CAL AUTOCAL
3* PUMP Pump
4 ESC Escape
5 ↑ Up arrow
6 ↓ Down arrow Reduce selected digit;
7 → Right arrow
8 ENTER Enter
* The input is suppressed if certain conditions are fulfilled.
A corresponding message is then output briefly on the display.
You can use the arrow keys to modify numerical values by increasing or decreasing the digit
at which the cursor is located. The digits are modified continuously, i.e. 0 follows again after
digit 9. You can also decrement to 9, 8... following digit 0. The analyzer outputs the value
FFF... if incorrect numbers are entered.
Use of the <MEAS>, <ESC>, and <ENTER> keys is described using examples in section
Key operations step by step (Page 98). Use of the <CAL> key is described in section The
CAL key (Page 101), use of the <PUMP> key in section The PUMP key (Page 102).
