PowerWatch VDR Features
The PowerWatch Voltage® Disturbance Recorder (VDR) is an easy-to use, low-cost power
quality analysis tool that troubleshoots power line disturbances such as surges, sags,
impulses, outages and frequency variations.
It is self-powered and easy to use - parameters can be set easily via your PC. The VDR can
retain 4,000 events. The existence of recorded events can be indicated by the VDR's flashing
light. Communication between a PC and the VDR is carried via the Lite-Link interface cable.
By using this optical data transfer, the PC remains electrically isolated.

Safety Precautions
Warning! The VDR is designed and certified to work only on single-phase systems.
Attempting to modify the VDR or operating it improperly may cause circuit damage
which can ultimately result in property damage, personal injury, or death.
2.2.2
Plugging in a PowerWatch VDR
The VDR does not use a protective earth connection since there are no exposed metal parts.
The earth conductor is used to measure neutral to ground (N-G) events. The ground prong
may be electrically unconnected (as long as it is not exposed). The VDR does not normally
need any special ventilation, however, its ambient temperature should not be allowed to rise
above the operating limit [see 2.2.9].
2.2.3
Electrical Immunity
The VDR's internal circuitry is solid-state with built-in EMI and RFI protection to ensure
reliable readings.
2.2.4
Safety Inspection
We recommend that you inspect the VDR periodically for visible damage. To ensure that it
operates safely, inspect for missing labels, cracks in the case, or bent blades and/or broken
leads.
2.2.5
Battery Care
The VDR contains a lithium battery that will, under normal circumstances, allow the VDR to
operate for 10 years. Exposing the VDR to extreme temperatures for extended periods of
time may reduce battery life by as much as 50%. The VDR is designed for INDOOR USE. It
should not be exposed to direct sunlight.
To extend battery life, keep the VDR plugged into a standard convenience outlet even when
not in use.

WARNING: BATTERY POSES FIRE, EXPLOSION AND SEVERE BURN HAZARD. DO NOT
RECHARGE, DISASSEMBLE, HEAT ABOVE 100°C (212°F), INCINERATE, OR EXPOSE
CONTENTS TO WATER
2.2.6
Maintenance
The PowerWatch® VDR is a maintenance-free product. However, it is recommended that it
be kept clean to allow for easy visual inspections. To clean the VDR, unplug it from the
outlet and wipe it with a dry, clean cloth.
2.2.7
Product Service
The PowerWatch® VDR has no user-serviceable parts inside. The fuse inside the VDR is NOT
OPERATOR REPLACEABLE. Opening the case, or attempting to do so, will void the warranty
and safety certification. The lite-link cable is the only replaceable part. If you require
service, please contact your local dealer or factory representative.

Calibration
This option is provided for advanced users only and is disabled by default. Changing the
calibration value of the PowerWatch VDR is not expected to be necessary under normal
conditions.
However, if the user believes the VDR’s real-time voltage reading could be improved, the
following procedure can be followed to re-calibrate the Hot-Neutral voltage.
No calibration for the Neutral-Ground voltage is provided, as this voltage should be 0V under
normal conditions.
Before adjusting the logger's calibration, you will need the following:
· a stable AC power source
· a calibrated multimeter (to verify the voltage of the AC source)
Warning! Inserting anything into an electrical socket can be dangerous, potentially causing
serious injury or death and should only be attempted by qualified personnel. ACR assumes
no liability in relation to this action by non-qualified persons.
The calibration procedure is as follows:
1. Click “Enable Calibration” on the Options Menu to enable the calibrate field of the device
Window
2. Enter the voltage measured on the multimeter in the calibration text box
3. Click the Calibrate button
If the real-time reading of the VDR is sufficiently different from the measured value, the VDR
will perform one or more iterations of calibration. The progress of this operation is
displayed on the communication window. When complete, a message window will appear
indicating this.

Event No. Column
The Event No. column displays the number sequence of each event, with the most recent
events displayed first. By using the scroll bar on the right of the window, all the events that
the VDR has recorded can be viewed. The number 0 is given to an Open Event.
5.4.1.2
Start Time Column
The Start Time column displays the time that an event started.
The Start Time is with respect to the current time of the downloading computer’s clock. If
the same VDR was downloaded on two different computers with their clocks set 1 minute
apart, there would be a difference of 1 minute in the start times of the events downloaded
on the two computers.
The resolution of the time stamp in a VDR is eight seconds.
If an impulse occurred once every second starting at 12:00:00, the first eight impulses would
all be reported to have the same time of 12:00:00. The next eight impulses would be
reported as having the same time of 12:00:08.
If identical information was downloaded twice from a VDR, the two data reports could show
a time difference of eight seconds.

End Time/Duration/Degree Column
The information recorded in this column is context sensitive.
For impulse events, this column indicates the phase angle of the impulse in degrees.
For all other event types, this column shows the duration of the event.
· Outages up to 16 seconds are recorded in 0.5 cycle resolution, otherwise the outage
resolution is eight seconds.
The format of the event duration for other event types is as follows:
· Events of less than one second are displayed in number of cycles.
· Events of one to 119 seconds are displayed in seconds.
· Events of between two minutes and 24 hours are displayed in hours, minutes and
seconds for example, 07:51:24 (7 hours, 51 minutes, and 24 seconds).
· Events that last longer than 24 hours display the end time (date and time).
An event which has not yet terminated is reported as Open Event.

Open Event
If an event was still in progress when data was downloaded from the VDR, the event will be
designated as an open event. Open events are assigned the number zero in the Event #
column.
PowerWatch can display one each of three open event types simultaneously, corresponding
to a surge on both Not-Neutral and Neutral-Ground and a frequency event.

Impulse Events
Impulses are transient voltage fluctuations (sometimes called spikes). They can be positive
or negative, and can occur on either the hot-neutral line or the neutral-ground line. The
voltage potential of an impulse can be quite large; hundreds of volts is not uncommon.
Impulses typically have a duration far below one cycle time and can be detected with a
duration of 1 microsecond or greater. Any voltage deviation above the impulse threshold and
less than one half cycle duration will be recorded as an impulse.
PowerWatch can detect both positive and negative impulses. An impulse event can include
one or more impulses occurring within the same half cycle. The event column will display the
number of impulses that the PowerWatch was able to count.
An important point to note about a multiple impulse event is that the voltage reading in the
Extreme column will be the total voltage of any impulses that occur more than 100
microseconds apart. When multiple impulses of different polarity occur, their absolute
values are added together. The degree (in the fourth column) will be the position in the cycle
of the first impulse. The angle of neutral-ground impulses is referenced to the start of the
hot-neutral sine wave.
If an impulse is less than one microsecond in length, PowerWatch will measure the
magnitude of the impulse but may be unable to determine the polarity. In this case,
PowerWatch will show the sign of the impulse as "+" .

PowerWatch® VDR & EventReader™ Software Reference Guide
Sag Events
Sags are decreases in line voltage lasting for at least one cycle. Sags are only measured on
the hot-neutral lines. Typically, a sag will range from a few volts to tens of volts below
normal.
If the voltage drops below the sag threshold, a sag event will be recorded. If it drops below
70V, the event will be recorded by PowerWatch as an outage.

Surge Events
Surges are increases in line voltage that last at least one full cycle. Surges can occur on both
the hot-neutral line or neutral-ground line.
Typically, surges are in the order of tens of volts and last from several cycles to several
seconds.
If the voltage exceeds the surge voltage threshold for longer than one cycle, a surge event
will be recorded.

Outage Events
When PowerWatch records a sag of below 70Vrms for longer than a second it displays the
event as an outage. The VDR will go into self-powered mode (battery) and will sample the
voltage every eight seconds. As a result, the shortest outage it will record will be eight
seconds. When the power is reapplied to PowerWatch, the VDR will not detect it
immediately, but will wait until the next eight-second sample before returning to the line
powered operational mode. This delay will prevent contact bounce being reported as an
event when PowerWatch is plugged into a standard electrical outlet.
Since PowerWatch's eight-second clock is not synchronized with outages, it can sometimes
report an outage as 16 seconds when in fact the outage only lasted for slightly over one
second. An example of when this would happen is if a sag below 70Vrms occurred 6.9
seconds into an eight-second period. At the 7.9-second point, PowerWatch would change to
self-powered mode and report a minimum outage of eight seconds. If then, at the 8.1-second
point, power was restored, the VDR would not sample again until the 16-second
point.

Frequency Events
Frequency events are variations in frequency above or below the nominal frequency (for
example, 60Hz in North America and 50Hz in Europe). Variations in frequency are typically a
few cycles and can be from seconds to minutes in duration.
If the frequency drops below the minimum threshold a low frequency event will be recorded;
if it exceeds the maximum threshold a high frequency event will be recorded.
The factory default nominal frequency is 60Hz for 110V models and 50Hz for 220V models.
However, PowerWatch can be user configured to record at 50Hz and 60Hz for either 110V or
240V models.

Loss of Synchronization Events
Excessive harmonics or noise on a power line may cause severely distorted voltage
waveforms. While not common, these distorted waveforms could result in "extra" zero
crossings on the AC line.
PowerWatch synchronizes itself to the consecutive positive and negative zero crossings of
the AC line (every 8.33 milliseconds at 60Hz). Should the voltage waveform be so highly
distorted that unexpected zero crossings are detected, PowerWatch will report a loss of
synchronization relative to the measured voltage waveform.
This Loss of Synchronization will be recorded as an event unless the measured voltage falls
below 70V (140V for 220V models), in which case, the event will be recorded as an outage
with a start time equal to the original loss of synchronization event.

6.1
COM Port
Many manufacturers of PC software and hardware use serial (COM) port(s). It is difficult to predict
potential serial port conflicts. If the Lite-Link interface cable's wand tip is not flashing, there are a
few steps that can be taken in order to potentially find the source of the problem.
· Make sure that the Lite-Link interface cable is securely plugged in. The Lite-Link may appear to
be properly connected but only be partially plugged in.
· Try a different serial port. If the PC has more than one serial port, try another port to see if the
Lite-Link flashes.
· Determine if you have any other Windows programs using the serial port. PC faxing programs or
other programs that use the COM port can cause conflicts during data transmission. To verify that
no other programs are running and causing communication problems, shut down your computer
and restart if before you run the EventReader application.
· Verify that your serial port settings are correct. Verify port settings using Device Manager.
Device Manager is found on the Task Bar by choosing Start, Control Panel, and Device Manager.

PowerWatch® VDR & EventReader™ Software Reference Guide
· Verify that your serial port is functioning properly. Use any standard Windows communications
program to ensure the port is functioning. Examples include: ProComm, Windows 3.1 Terminal or
Windows 95 Hyper Terminal.
Exit all programs (including EventReader) and connect the Lite-Link to the port. Run the
communications software and set the local echo to "off" and hardware flow control to "none".
Any alphanumeric character typed on the keyboard should cause the Lite-Link to flash, and the
character to appear on the screen.
If the Lite-Link does not flash during typing, the Lite-Link may need repair.
If the Lite-Link flashes during typing, it should also work with EventReader software. Exit the
communications program, and re-start EventReader. If Lite-Link does not flash when running
EventReader, re-install EventReader software.
· Check your mouse driver. Certain older or inferior drivers for mice, trackballs, and laptop
"pointers" are known to interfere with serial port operation. If, after disabling your mouse driver,
the Lite-Link functions normally, try using a high quality mouse driver such as Logitech or
Microsoft.
· Try another computer. An alternative to serial port troubleshooting is to use a different
computer. Another computer with its serial ports set up correctly will confirm that there is an
incorrect set up or software/hardware conflict with the original PC.
6.2
Printers
· Verify that the printer is plugged in, turned on, has paper, and is connected either directly to the
PC or to a LAN.
· Verify that Windows is set up correctly. Windows uses its own printer drivers. Set up is done
through the Devices and Printers section of the Control Panel. If you need help, follow the
instructions in the Windows Help and Support section. Specifically "Troubleshooting Printers".
· Try printing from another program to eliminate the possibility of a hardware conflict.

Troubleshooting
6.3.1
65
PowerWatch voltage readings are different from other meters
Possible solution 1: A PowerWatch VDR reads voltage in average RMS, while some
manufacturers' meters may calculate and display True RMS.
Possible solution 2: Re-calibrate the VDR [see 5.2.1.6]
6.3.2
Date and/or time are not correct
The PowerWatch uses the PC's internal clock to reference the time of the downloaded data. Set
the PC's internal clock to the current time. To adjust the date/time in Windows, right click on the
clock in the system tray and choose "Adjust date/time".
6.3.3
PowerWatch time stamps are invalid after a prolonged period of time
To eliminate this issue, ensure that the PowerWatch VDR is cleared of data a minimum of once
every four years.
6.3.4
Two PowerWatch units have different impulse readings on the same circuit
Locally generated impulses can carry relatively little power. One VDR can absorb some of the
energy leaving less for the next one in the series to read.
6.3.5
PowerWatch records long periods of large NG surge
The VDR has been plugged into a convenience outlet that has been wired with the hot and
neutral lines reversed. This event can usually be eliminated by setting the Neutral-Ground surge
threshold to the maximum value. Impulses on Neutral-Ground will still be recorded in this
situation.

6.3.6
PowerWatch® VDR & EventReader™ Software Reference Guide
PowerWatch does not record any data
Possible solution 1: The VDR does not record events while communicating. Make sure that realtime display is stopped. PowerWatch will record events in 8 to 16 seconds thereafter.
Possible solution 2: Ensure the threshold settings are low enough to capture the event.
