TIMING RANGE
ADJUSTABLE              (For operation code B, F and W)
Code 1001: 0.1 to 1 second          Rx = (T / to -1) x 100kohm
Code 1002: 1 to 10 seconds
Code 1003: 10 to 100 seconds
Code 1004: 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         300 s --> Code 3003
