1. FEATURES AND FUNCTIONS
Chapter 1 FEATURES AND FUNCTIONS
This chapter describes the main features and functions of the µR1800 recorder. The
µR1800 is equipped with all the functions which can be expected in a modern recorder,
whereas its functions also reflect the latest user requirements.
1.1 Features
The µR1800 recorder is a precision measuring instrument that is equipped with many
outstanding features:
Compact sized, high reliability: Its compact size (depth 220mm) allows you to
install the µR1800 where only a limited space is available. In case of the pen model, a
contact-free potentiometer and a brushless-DC servomotor contribute to its high
reliability. In case of the dot printing model, high reliability is obtained by the use of
high break down voltage solid-state relays.
Universal inputs: Inputs like DC-voltage, Thermocouple (TC), Resistance
Temperature Detector (RTD), and Digital Input (contact) can all be conveniently used.
There is no need to change any dipswitches; the type of input can be set using the key-
board.
Easy interactive setting: The setting procedure has been made very easy, by using
only panel keys. The µR1800 asks you to select the desired settings, without the need
for remembering difficult setting-codes.
Large informative operator display: The large sized, VFD, display shows the
measured data (including the engineering units) or clock, and bargraph at the same time.
There are two types of bargraph available: percentage-display, and center-zero display.
Because of its 1%-resolution, the bargraph displays very accurately.
Continuous pen recording for up to four channels (pen model only):
Depending on your µR1800 model type, the µR1800 can measure up to four channels
simultaneously. This allows you to decrease the number of recorders you require.
Universal power supply (except for /P1 model): The µR1800 accepts 90 to
250VAC (except 132 to 180VAC), and 50/60Hz without any problems, or need to turn
switches. Therefore the µR1800 is compatible with a wide variety of power supplies.
High performance: The sampling speed of the µR1800 pen model is high at 125 ms,
whereas the recording cycle of the µR1800 dot printing model is 6 ch./10 seconds, or
12ch./15sec., 18ch./20sec. or 24ch./30sec. depending on the model.
The µR1800 is equipped with many functions. Special functions can be ordered as an
option. Furthermore, its power consumption is low (4pen model; 30VA under normal
operation conditions).
Easy maintenance: Because of the use of many contact-free parts, the need for
maintenance has been decreased. The µR1800 is designed in modules, which decreases
the time needed for maintenance extensively.
Closed case: The closed case of the µR1800 allows it to be used in many
environments. The front door is in accordance with DIN 40050-IP54.
Computer interface and memory card: If equipped with this option, the µR1800
can store and retrieve measured data as well as setting data, using an IC memory card or
directly from your PC. The available interface is RS-422-A.
Based on international safety standards: The µR1800 (except portable type) is
based on international safety standards, such as the IEC 348.

3.2.2 Power Supply Wiring
1Make sure the power switch is turned OFF and remove the transparent cover at the
rear of the µR1800.
2Connect the power supply wires and the protective ground wire to the power terminals
and the ground terminals as shown in figure 3.4.
3Replace the transparent cover.
Figure 3.4 Power Supply Wiring
NOTE •Do not apply power supply of 132 to 180VAC. This might affect the measuring
accuracy.
•In case of portable type, plug the female end of power cord into the socket on the rear
panel.
•To prevent an emission of electromagnetic disturbances, separate the power supply
wires from the other wires at least 0.1m. Over 0.5m is recommended.
To prevent an electric shock, ensure the main power supply is turned OFF and
connect the ground terminal using a class 3 resistance of 100Ωor less.
For power and ground wiring termination, use “crimp on” lugs (for 4mm screws)
with insulation sleeves (see figure 3.5).
To prevent fire, use 600V PVC insulated wire (AWG18) for power and ground
wiring (cross sectional area of 0.83mm2or thicker, anti-galvanic corrosion finish,
insulation thickness should be more than 0.8mm, insulation resistance should
be more than 50MΩKm at 20°C, approved EN60 320 (VDE0625), and do not
remove the transparent cover.
Make sure to apply a power switch in the power supply cord with the following
characteristics:
Others than /P1 model
• rated power current > 1A
•rated rush current > 60A
• fuse(s) of 2A to 15A is (are) necessary.
/P1 model
• rated power current > 3A
•rated rush current > 70A
• fuse(s) of 5A to 15A is (are) necessary.
The power switch and fuse used in the power supply cord should be
•CSA approved (for use in North America)
•VDE approved (for use in Europe).

3.2.3 Input Wiring
1Make sure the power switch is turned OFF and remove the transparent cover at the
rear of the µR1800.
2Connect the input wires to the input terminal.
3Replace the transparent cover.
It is recommended that “crimp on” lugs (for 4mm screws) with insulation sleeves be
used for leadwire ends. See figure 3.5.
In case of clamped input terminals, do not use “crimp on” lugs.
Since the input terminal will be affected by changes in temperature (e.g. because of
wind), make sure to replace the transparent cover after wiring.
Even after replacement, take care not to expose the terminals to fans, etc.
Suggestions to minimize noise pickup:
•The measuring circuit wiring should be run as remote as possible from the power
and ground wires.
•It is recommended that shielded wires be used to minimize noise pickup from an
electrostatic induction source. The shielding wire of the cable should be connected
to the µR1800 ground terminal (only one ground line).
• To minimize noise from an electromagnetic induction source, twist the measuring
line cables in short and equal spaces.
•The to be measured object should be free from noise. However, if it isn’t, make
sure the measuring circuit is isolated and the to be measured object is grounded.
If TC and RJC is used, the temperature of the input terminals should be as stable as
possible. Therefore, make sure to use the transparent cover. The thermal capacity of
the wiring should be small (recommended ø ≤ 0.3mm).
Refrain from wiring the input parallel. However, if you do, then
•do not use the burnout function
•ground the equipments at the same point
•turning ON/OFF the power might cause malfunction
•RTD cannot be wired parallel.
To prevent an electric shock, ensure the main power supply is turned OFF
and connect the ground terminal using a class 3 resistance of 100Ωor less.
If you have an input of DC ≤2V or a TC, don’t apply an input voltage ex-
ceeding ±10VDC.
Do not apply a max. common mode voltage more than 250VAC rms (50/
60Hz). The recorder and measured values will be adversely affected.
Add following to 'CAUTION'
This instrument complies with Inatallation Category ll.
NOTE To prevent an emission of electromagnetic disturbances, separate the input wires from
the other wires at least 0.1m. Over 0.5m is recommended.
