(For operation code B, F and W)
0.1 to 1 second
Rx = (T / to -1) x 100kohm
1 to 10 seconds
10 to 100 seconds
100 to 1000 seconds
where Rx in kohms T: desired time in seconds,
to: time measured with Rx = 0.
Example to determine Rx value for a T time of 5 seconds:
Choose code 1002; measure time with
Rx = 0 (for example : to = 1 s); calculate Rx = (5/1 - 1) x 100000
Theoretical resistance: Rx = 400 kohms
FIXED
The timing code consists of 4 digits. To determine this code, convert the value to milliseconds
value. Use the first 3 digits of this value and add a fourth digit to indicate the number of
zeros which must follow the three digits to show complete milliseconds value.
Examples: 250 ms --> Code 2500
Date of issue: 3/06
300 s --> Code 3003
