8.3 Memory
The active programmings are indicated in the meas-
uring menu. The first line in the example opposite
displays the following code:
A = active, P:1 = Program 1, e = start crit. extern. signal
A = Active
P:1 - P:3 = Active program 1 - 3
e = External trigger / external signal
t = Time trigger / time plan
w = Value trigger / Overrun/Underrun etc.
w = Difference
w = Gradient
P.2:321: = Program 2 is running, 321 values are
currently saved (in this protocol)
You can start the following from the measuring menu:
- program 1 with <1> key
- program 2 with <2> key
- program 3 with <3> key.
8.3.4 Minimum rate
The “M
IN. RATE” menu shows the specified minimum
rate of the probes connected. This value cannot be
underrun when programming the instrument.
Select “M
IN.RATE” from the memory menu list and
confirm with <Enter>.

Function required Here´s how....
Start program with instrument - Select program
switched on - Switch off Auto Off function (See
Chapter 8.6.4)
- Check charge in rechargeable batteries or
connect mains unit
Start program with instrument
switched off
Starting criterion: Time plan or trigger - Carry out settings
- Switch off instrument
Starting criterion: Overrun/underrun - Set limit values and parameter
or gradient or difference - Set and activate intermediate rate
- Switch off instrument
Note: Activated measuring programs (P1 – P3), which take measured values as the basis
for starting criterion, are executed with the instrument switched off only if the intermediate
rate and the measuring rate are set at more than 1 minute. For rates of less than 60 sec-
onds the instrument must be switched on to start the measuring program. The Auto-Off
function then has to be deactivated.
