When the tolali/er is used Jor lolul ñow mea^urcmeni, per-count (pulse) value is (he
counting me, PuJsje output is also available forCTiiernal total ization. Jn this item, the
counting rate and the pulse width for pulse output can be checked or changed. I’hc
couniing rate is set using three digits and exponential quotient,
bor example, 0.123 m'' 1.23b-l
(1.23 X 11)^ m')
Proceed as follows to check or change the counting rate.
