User Manual
Ruggedly design for prolonged use as both a 
bench-top count-up timer and a stopclock.  
Non-skid feet keep the unit rmly in place during 
use, yet it is small and light enough to be easily 
moved around the lab as needed. A large LCD 
and buttons make it easy to operate. Counts-
up to 10 hours with 1/100th second resolution 
in selectable cumulative or interval split modes. 
Comes complete with one AA battery and two 
cables for connection to an external trigger 
such as a photo gate. This unit is CE approved 
and available with NIST traceable certicate of 
calibration (810032C).
