Installation and
Operating Instructions
Integra Ri3
DIN-rail digital meter for single
and three-phase electrical systems
Caution:
consult instructions before installation or use
Introduction
This unit measures and displays the characteristics of single-phase
two-wire, three-phase three-wire and three-phase four-wire
supplies, including voltage, frequency, current, power and real and
reactive energy, imported and exported.
For more in-depth operating instructions, please refer to the full
manual that is available on the Crompton Instruments website, at
www.crompton-instruments.com
.
Measurement
In measurement mode, the buttons control the displayed
measurement as follows:
Selects the Voltage and Frequency display screens.
Successive operations of the button select voltage,
frequency and %THD (Total Harmonic Distortion).
In Set-
up mode, this is the ‘Back’ button.
Selects the Current display screens. Successive
operations select phase and neutral (3ph4w) currents,
max. demanded currents and current %THD.
In Set-
up mode, this is the ‘Up’ button.
Selects the Instantaneous Power screens. Successive
operations select power (W, VAr & VA), max.
demanded power and power factor.
In Set-
up mode, this is the ‘Down’ button.
Selects the Energy display screens. Successive
operations select imported/exported Wh and Varh.
Display can indicate up to 9999999·9.
Running man symbol flashes as data accumulates.
1% symbol shows that power values of <1% of range
maximum will be included in energy readings.
In Set-
up mode, this is the ‘Enter’ button.
Display shows the units of measurements in use for each range.
Energy units can be set via set-up screens; other units are set
automatically.
A Demand Reset resets maximum demand readings to zero.
Setting up
To enter set-up mode, firmly press the
and
buttons
simultaneously and hold for 5 seconds, until the password screen
appears. Setting up is password-protected so you must enter the
correc
t password (default ‘0000’) before proceeding. If an incorrect
password is entered, the display reverts to measurement mode.
To exit setting-up mode, press
repeatedly until the
measurement screen is restored or hold
and
buttons
simultaneously for 5 seconds.

Menu Option Selection
1.
Use the
(up) and
(down) keys to select the required
item from the menu. Selection does not roll over between
bottom and top of list.
2.
Press
to confirm the selection.
3.
If an item flashes, then it can be adjusted by the
(up) and
(down) keys. If not, there may be a further layer, e.g.
Comms - Baud rate, before adjustment is possible. Press
to select the lower layer.
4.
Having selected an option from the current menu layer, press
to confirm your selection. The SET indicator will appear.
5.
Having completed a parameter setting, press
to return to
a higher menu level. The SET indicator will be removed and
you will be able to use the
and
keys for further
menu selection.
6.
On completion of all setting-up, press
repeatedly until the
measurement screen is restored.
Number Entry Procedure
When setting up the unit, some screens require the entering of a
number. In particular, on entry to the setting up section, a
password must be entered. Digits are set individually, from left to
right. The procedure is as follows:
1.
The current digit to be set flashes and is set using the
(up) and
(down) keys.
2.
Press
to confirm each digit setting. The SET indicator
appears after the last digit has been set.
3.
After setting the last digit, press
to exit the number
setting routine. The SET indicator will be removed.
