Buzzer feature to have audible level tone in proportion
to level measured for hands-free operations. |

Option :
Software for pc interface. TELM 1.01
This software enables user to
1. remotely operate Level Master I or II , from serial port
of pc.
2. Data Acquisition from remote operation for later printing
and analysis os stored readouts.
3. Real time monitoring of all channels by visual indication
in form of bar graph or red colours to indicate the signal
levels of the channels, which are above or below the set value
of desired level.
This feature is very useful in the headend(control room).
For example if the signal level of any channel drops to zero
or very low level, it indicates the failure of that channel
or program by red colours indication, and without such an
arrangement, it is very difficult to know The failure of one
channel or program out of many channels (as many as 70 to
100 , now a days.) this feature helps to keep the customers
happy, because before the customers complain about any failure
of program, the owner of the catv network gets chance to correct
the failure.
