OTHER NOTES

In order to ensure data reliability of the SDP interface, DP-1VR reads the data twice.
Some models (KC counter with code out unit No. 09CAA462 etc.) are incapable of
performing the above data checking routine.
For those models, you must perform the following procedures by changing the
interface mode.
Interface mode is interchangeable with the former products (DP-1HS) by setting it for
COMPATIBLE.

MAINTENANCE

Daily maintenance of DP-1VR

Clean printer head
When dust collects on the printer head, print quality is adversely affected, and
sometimes printing is impossible due to damage to the printer head. It is recommended cleaning the printer head periodically.
Cleaning method:
After opening the printer cover the printer head can be seen. Rub the printer head
with a cotton swab soaked in a little alcohol. After that, wipe off the remaining
alcohol lightly with a dry cotton swab until dry.

Clean paper sensor
If the paper sensor becomes dirty, detection of the record paper is impossible and
normal operation can not be conducted. It is recommended to clean the paper sensor
portion periodically.
Cleaning method:
After opening the printer cover the printer sensor can be seen. Rub the printer sensor
with a cotton swab soaked in a little alcohol. After that, wipe off the remaining
alcohol lightly with a dry cotton swab until completely dry.

◆ Just after finishing printing, do not clean. Printer head is hot; you may burn
your hand. Also, that heat may set the alcohol on fire.
◆ Alcohol left on the head should be dried completely, since there is a possibility
it could ignite.
◆ Handle the alcohol carefully.
◆ Do not use thinners, benzene etc., only use alcohol.

Overflow and calculation error
●

Overflow and calculation error
Overflow conditions of DP-1VR and calculation error are shown below:
Overflow of DP-1VR is different due to mean value and amount of data.
This is shown in the graph overflow condition.

●

Viewpoint of graph
If mean value 10 m is measured with 2 figures after the decimal point (by caliper
etc.), how much of data can be measured, is checked.
q

Data 10000.00 is changed to 1000000 as no decimal point.

Vertical axis 1000000 on graph is extended to the horizontal direction and
compared to the horizontal axis.

2000 is obtained as the number of the data.

When the data of the mean value 10 m is measured about 2000, it is recognized that the overflow happens.

IMPORTANT
◆ Overflow seldom happens in usual measurement by calipers or micrometers
etc.
◆ When this unit is used for printing of a linear scale counter, overflow may
happen. Be careful when referring to a graph of this condition that overflow
may happen.

CALCULATION METHOD
NOTE
◆ Mean value of the data shows the state when the decimal point of the data is
neglected.
Ex 10.00 is changed to read 1000

Calculation error detail
Calculation error of DP-1VR is shown below:
Calculation error of DP-1VR is defined as follows.
q

Last figure ±1 count. Graph expresses the inside of the overflow limit of the
calculation preciseness.
Dispersion of data is set at ±5% of the mean value.

When the dispersion of the mean value is far beyond the mentioned value,
calculation error is over ±5.

For A region (±1000000, data count less than 2000), in all cases, calculation error
is less than ±1.
