I Front view with operating controls
a Adjustment of the time range (depending on the device)
by selecting the max. value of the desired time range:
Time range:
0.05 - 1 s =
0.5 - 10 s =
5 - 100 s =
0.5 - 10 min =
5 - 100 min =
0.5 - 10 h =
5 - 100 h =
b Direct reading scale to set the time value within the
chosen range
Calculation of the time value:
"Range"
1 s
10 s, 10 m, 10 h
100 s, 100 m, 100 h
Example 1:
Time value to set: 0.5 s
Select 1 s on scale "Range"
Select 5 on scale "Time"
5 x 0.1 = 0.5 s
Example 2:
Time value to set: 80 s
Select 100 s on scale "Range"
Select 8 on scale "Time"
8 x 10 = 80 s
