1. APPLICATION AND METER DESIGN
The programmable digital panel meter DHB-1xx is destined for me-
asurements: number of pulses, frequency, period, worktime, encoder
position. Additionally, the meter enables the indication of the current
time. The readout field is a LED display, which allows the exposition
in colours: red, green and orange. The measured input signal can be
arbitrary converted by means of mathematic functions and/or a 21-point
individual characteristic.
Features of the DHB-1xx Meter:
l
display colour individually programmed in three ranges,
l
programmable thresholds of displayed overflows,
l
2 NOC relay alarms operating in 6 modes,
l
2 switched relay alarms with a switching contact operating
in 6 modes (DHB-124),
l
signaling of measuring range overflow,
l
automatic setting of the decimal point,
l
programming of alarms and analog outputs with the reaction
on the selected input quantity (main or auxiliary input),
l
additional counter input,
l
control inputs of the main input work, additional or both simultaneously,
l
signaling of additional input state,
l
possible control of counter operation by means of the meter keyboard,
l
automatic reset of counters at the set point value
l
real-time clock with the function of the clock supply support in case
of the meter supply decay,
l
programmed averaging time – function of walking window with the
averaging time up to 1 hour,
l
monitoring of set parameter values,
l
locking of introduced parameters by means of a password,
l
mathematic functions for measured value calculation,
l
recount of the measured quantity on the base of the 21-point
individual characteristic,
