1. Power Supply

 The power is supplied via an AC adapter or four AA nickel-metal-

hydride (Ni-MH) batteries or alkaline batteries (LR6).

 If both batteries and an AC adapter are set, power supply from the

AC adapter is given priority. (Batteries are not supplied.) Batteries
cannot be charged from the AC adapter, so use a dedicated battery
charger for battery charging.

 If the voltage drops during battery use or if an AC adapter other than

the one that is provided is used, the power LED will blink to indicate
an anomaly.

1.1 Setting the batteries

Set the batteries. If using the AC adapter, refer to section 1.2.

<1> Open the battery compartment.

Press the battery compartment by pressing the lock release and

pull the compartment lid off.

MH AA) batteries in the battery compartment, making sure to

orient them correctly.

back the battery compartment lid into place until you hear a click.

 Be sure to correctly orient the batteries.
 Do not mix different types of batteries.
 Use either size AA alkaline batteries (LR6) or size AA

nickel-metal-hydride (Ni-MH AA).

 Do not use manganese batteries.
 If alkaline batteries are used, printouts may look faint

due to the characteristics of such batteries.

 When using alkaline batteries or Ni-MH batteries, the

printing speed may be slower compared to when the AC
adapter is used.

 If batteries are used, any exfoliation or swelling of the

coating on battery terminals may cause bad contact or a
short circuit. Make sure that the batteries are free of
exfoliation and swelling before using them.

 If the DP-1VR will not be used for a long period of time,

remove the batteries from the battery compartment. If
the batteries are left inside the DP-1VR, battery leaks
may render the DP-1VR unusable.

 Batteries can be used as the power supply when the

temperature is 10C or higher. At temperatures lower
than 10C, faint printouts and other problems may
occur.

ADDENDA

 The DP-1VR does not have a charging function. Use a

dedicated charger for battery charging.

 The battery life of the DP-1VR is approximately 10,000

lines (when printing in large size once every 5 s using
1600 mAh Ni-MH batteries).

OPERATION

 To enter the limit input mode, the DP-1VR must be in one of

the following two states: <1> Data immediately following
power on not input, or <2> all the data cleared with the [CL]
key.

 In the limit input mode, limit data is switched using the [STAT]

key. Up to 5 sets of limit data can be saved. Switch the limit
data as needed.

 When a number corresponding to already set limit data is

selected and limit data is then newly input, the new data is
overwritten on the old data and the old data ceases to exist.

 Limit dat a remains saved even after the power is switched off.
 Immediately after the power is switched on, the limit data that

was being used at the time the power was switched off is
selected.

 If no limit data is required (if limit judgment is not required),

either select a limit number for which no limit data has been
input (refer to 3.2), or delete the limit data (refer to 3.3.)

MAINTENANCE

This chapter describes the daily maintenance of the DP-1VR.

1. Cleaning the Printer Head

Dirt adhering to the printer head may result in poor printing quality and
damage the printer head, making printing altogether impossible. It is
therefore recommended to clean the printer head on a regular basis.
Cleaning method:
Open the printer cover and gently wipe the printer head with a cotton
swab moistened with a little alcohol. Then wipe off any alcohol
remaining on the printer head with a dry cotton swab.

2. Cleaning the Paper Sensor

A dirty paper sensor may render printer paper detection impossible and
prevent normal operation. It is thus recommended to clean the paper
sensor on a regular basis.
Cleaning method:
Open the printer cover and gently wipe the paper sensor with a cotton
swab moistened with a little alcohol. Then wipe off any alcohol
remaining on the printer head with a dry cotton swab to make sure it is
fully dry.

 Never perform cleaning immediately after printing, because

the printer head will still be very hot and may cause burns.

CAUTION

This also presents the risk of the alcohol igniting.

 Thoroughly wipe off any alcohol that remains on the

printer head. Powering on the DP-1VR while the printer
head is not completely dry may cause a fire.

 Handle the alcohol used for cleaning with care.
 Never use thinner, benzene, or some other substance

instead of alcohol.

 When the DP-1VR is turned off, all the saved data is

deleted. Also note that if the AC adapter is disconnected
while the DP-1VR is being used (regardless of whether
or not the DP-1VR is powered via the AC adapter), all the
data saved until then is lost.

 When operating the DP-1VR on batteries, if the room

temperature drops below 10C, the battery life becomes
considerably shorter. Use an AC adapter when the room
temperature drops below 10C.

 When the batteries are used up, the voltage drops below

the operating voltage, so that the alarm lamp may not
function properly. If the alarm lamp blinks, change the
batteries as promptly as possible or switch to the AC
adapter.

2. Overflow and Processing Errors

 Overflow and processing errors
DP-1VR overflow conditions and processing errors are described below.
DP-1VR overflow varies according to the average value of data and the

number of data. This is illustrated in the Overflow Conditions graph below.

 Graph explanation
Assuming that an average value of 10 m is measured (with a caliper, etc.)

with two or more digits after the decimal point, let us see approximately how
many data can be measured.

<1> Data 10000.00 is expressed as 1000000 when expressed as data

without a decimal point.

<2> Horizontally extending the vertical axis on the graph yields the

horizontal axis of the graph.
<3> 2000 is obtained as the number of data.
<4> When data with an average value of 10 m is measured approximately

2000 times, overflow is observed.

 When using a caliper, micrometer, etc., overflow almost

never occurs.

 When using the DP-1VR as a linear scale counter

printer, overflow may occur. Therefore, referring to the
overflow occurrence conditions graph and appropriate
caution are required.

NOTE

 The notation format for average data values does not use a

decimal point.
Example: Read 10.00 as 1000.

3. Processing Error Details

The DP-1VR processing error is described below.
The DP-1VR processing error is defined as follows.

1. Lowermost digit 1 is counted but the value is on the inside of the
overflow limit indicated by the processing precision.
Data variation at this time is approximately 5% of the average
value.

2. The processing error when the average value variation greatly
exceeds the above variation is counted as lowermost digit 5.

3. However, regarding area A (1000000, number of data 2000 or
lower), in all cases the processing error is counted as lowermost
digit 1.
