| The
Microsolve single phase Volt Amp meter covers all the
requirements that you may have in an A.C. environment.
This state of the art instrument uses a 10 bit analogue
to digital microprocessor technology to bring you an
inexpensive yet reliable and accurate instrument. Designed
using the minimum of components for long term reliability,
the measuring algorithm takes approximately 400 readings
per second, yet the display is updated in such a manner
that the reading is comfortable on the eye. |
Single
Phase Volt / Amp Meters |
This
instrument has been specifically designed for voltage
supply monitoring in diverse applications such as motor
panels, process control, temperature control, in fact
any application in which the incoming voltage and current
supply needs to be monitored. |
|
The
instrument has been designed for a maximum input of
5 Amps. Higher currents will require the use of a instrument
Class 1 type of current transformer, with a secondary
ratio of 5 Amps. The display can be easily adjusted
to accommodate the ratio of the current transformer
by simply adjusting a 15 turn potentiometer on the main
board. Access to this potentiometer, requires the user
to remove the bezel and front plastic plate, and with
an insulated shaft mini screwdriver, rotate the potentiometer
until the desired current value is displayed. Setting
the decimal point is just as easy, simply move a jumper
to select the required position.

CARE
MUST BE TAKEN DURING THIS PROCEDURE, AS ALL POINTS OF
THE INSTRUMENT WILL BE AT LINE POTENTIAL |
| |
We
suggest that the current transformer ratio be known
at the time of ordering the instrument. |
monitoring
- DPM-VISA |
The input requires a common Neutral point connected
to mains and to the load through the internal 5 Amp
shunt.. The electronics power is fed from the Live and
Neutral connections. The top display will show the voltage
of that supply and the lower display will show the current..
The input supply can vary by as much as 30% with out
affecting the accuracy of the instrument. In the case
that the supply on the Neutral and Live phase drops
below 30%, the instrument will display a flashing '150'
on the two displays. |

monitoring - DPM-VIAA |
The
instrument is powered from an auxiliary supply, and
can monitor a single phase mains supply. Inputs of up
to 600V A.C. can be measured across the volts terminal.
The input requires a common Neutral point connected
to mains and to the load through the internal 5 Amp
shunt.. |
