These timers are microprocessor based digital timers and are very useful tomeasure closed, trip and trip-free timings of breakers.

FEATURES :

  Microprocessor based technology.
 Very compact and lightweight.
 Very accurate measurements.
 Economical.

TECHNICAL SPECIFICATIONS :

Range                       : Up to 999 millisecond.

Display                    : LCD type.

Accuracy                 : 0.5%.

Commands                : Close & trip for breakers.

                                   Trip free  : C O - C timing of breakers.

Reset                        : Resets the counter to zero.

Input                          : a) Potential free contacts across R-Y-B and common.

                                   b) +ve and close or +ve and trip can withstand for 220V AC/DC and 6 Amp.

Supply                       : 230V AC, single phase, 50Hz.

Enclosure                   : The instrument is housed in plastic molded cabinet.
 

SPECIAL NOTES :

The timer will not start if all three contacts are not in same condition.

The timer will not start for trip free mode if all poles are not open. Display will state the condition of each pole.

You can check the bounces when close command is issued. Once all the three phases closed change bounce
     switch to bounce position. The timer will scroll for R, Y, and B phase with indicating No. of bounces and close
      duration for each bounce.Duration is indication by a, b, c, and so on for 6 bounces. Each phase scrolled for                 approximately 6 seconds

If timer does not stop it will indicate that time has exceeded 10 seconds and it will be displayed according to phase.
