tion or damage. Ask the shop where you purchased the product or T&D Cor-

poration to carry out any repairs.

If water or a foreign body enters into this unit, immediately remove the batter-

ies and stop using. Continued use may cause ﬁre or electrocution.

Do not touch the input cable with wet hands or if there are water drops on the

cable. Depending on what you are measuring, this may cause electrocution.

Do not use this unit in wet or humid places, such as a bathroom.

Continued use may cause ﬁre, electrocution or damage.

Store all batteries, input cable, communication cable, and Voltage Recorder

units out of the reach of children.

It is dangerous to swallow batteries.

If any smoke or strange smells are emitted from the unit, immediately cease

using it. Continued use may cause ﬁre, electrocution or damage.

Do not drop the unit, or expose the unit to a strong impact. If that happens to

the unit, immediately remove the batteries and stop using.

Continued use may cause ﬁre or electrocution.

This device is designed to measure and record Voltage. Do not use it for any

other purpose than to measure and record Voltage.

The VR-71 uses a common ground for both channels, so when connecting

input cables be sure to connect the ground (black wire) for each channel to the

same.

Do not use any batteries other than AAA Alkaline batteries.

It may cause ﬁre or damage.

Condensation may occur if the unit is moved from one environment to another

where the difference in temperature is great. Use the unit in an environment

where the ambient temperature is from 0 to 50°C and the humidity is from

90%RH (no condensation) or less.

Battery life depends on the measurement environment, communication

frequency, recording interval and battery quality.

This unit is not water-resistant.

If the unit gets dirty, wipe it with a clean cloth and a mild detergent.

Do not expose the unit to harmful gases or chemicals. It may cause corrosion

and / or other danger to the unit and to people handling the unit.

If water or a foreign object enters the case, immediately cease using it.

CAUTION

The possible measuring range for this data logger is: ±15V with a maximum

input of ±20V. Connecting it to high voltage (AC 100V, etc...) may cause

damage to the logger and / or to the signal origin.

Do not remove the input cable from the logger and leave it while still connected

to the origin of the signal. There is a chance that it will come into contact with

another signal and cause a short.

Battery terminals may provide insufficient contact due to age or vibration.

Please be careful not to lose data due to insufﬁcient contact.

Remove batteries from any unit that will not be used for a long period of time.

Batteries left in a unit not being used for a long time may leak and cause a

malfunction.

Do not use or store the Thermo Recorder in any of the following places. Doing

so may cause electrocution, fire and/or other adverse effects to the device

and/or your computer.

Areas exposed to direct sunlight

This will cause the inside of the device to become overheated and may cause

ﬁre, deformation, and/or other damage including malfunction.

Areas prone to strong magnetic ﬁelds

This may cause damage including malfunction.

Areas exposed to water leakage

This may cause electrocution or other damage including malfunction.

Areas exposed to excessive vibration

This may cause injury, malfunction, damage or loss of proper electrical

contact.

Areas near ﬁre or exposed to excessive heat

This may cause damage including malfunction and deformation.

Areas prone to smoke, dust and dirt

This may cause damage including malfunction.

To prevent damage to the unit from static electricity, remove static electricity

from your body by touching metal around you (door knob, window frame)

before touching the unit. Static electricity may cause not only damage to the

unit, but may cause breaks in or a loss of data.

What is Voltage Recorder?

Overview

The data recorded into the Voltage Recorder units can be downloaded to your computer

with our exclusive software whereby you can easily process the data into graphs, tables,

save to ﬁles and / or print it out. Of course you can display the voltage reading as is, or by

using the software to select the desired scale, convert and display the readings in the unit

of your choice

Voltage Recorder VR-71 Basic Functions

Each Logger has 2 Measurement / Recording Channels

It's possible to simultaneously measure and record at two places with one logger. By pressing the

DISPLAY button on the logger, you can choose to set the LCD display to show both channels’

readings alternatively, show one channel as a ﬁxed display or show neither channel.

Voltage Measurement Range: DC±15V

Our input cables and probe can measure and record various output signals. The VR-7101 or VR-7102

(optional) can record signals of ±15V and our optional VR-7103 probe allows a range of 4 20mA.

Choose the Display Unit

It is possible using the software to create and edit dot matrix patterns to be used in the LCD as the

unit of measurement.

Recording Capacity : 8,000 readings x 2 channels

Each channel can record and store up to 8000 readings. At the longest recording interval of 60

minutes, recording can continue consecutively for 1 year.

There are 20 recording intervals / Shortest is 0.02 seconds.

There are 20 recording intervals (0.02 seconds to 60 minutes) to select from. There are two recording

modes to choose from: One Time and Endless.

9 Months of Continued Use on 2 AAA Batteries

Using our specially designed low energy consumption circuit this unit can run on two AAA alkaline

batteries for up to 9 months of continued use. No need to worry about where you place it as the

battery will allow you to measure and record over long periods of time whether the unit is in transit or

in a distant place.

Auto-Range Function / ± Input

You can manually set the range or you can set to have the auto-range function automatically select

the best range from the 4 input ranges ±1V, ±2V, ±6V, ±15V.

NOTE:

If the recording interval is 0.5 seconds or less the auto-range function cannot be used.

Preheat Function / Simultaneous Recording Function

The expansion unit (optional) allows you to transmit a preheat signal that is synchronized with the

VR-71 recording timing to turn sensors or other devices ON and OFF, and also allows you to

simultaneously record with up to 4 VR-71 units.
