Cleaning
Do not clean the instrument while the instrument is on.
Harsh abrasives, solvents, scouring cleaners and alkaline
cleaning solutions, such as washing soda, should not be
used especially on the display window. The outside of the
instrument may be wiped down with a slightly damp clean
cloth (lightly moistened with water only).
Under no circumstances should you attempt to wipe the
inside of the instrument.
Safety
This equipment is supplied by a mains voltage which can
cause an electric shock injury. Before removing the circuit
board from its housing, switch the instrument off, isolate it
from the mains power supply and make sure that it cannot
be connected inadvertently by other persons.
If the circuit board is removed from its housing, do not
apply power to the instrument unless specifically instructed
to do so in these instructions. When working on live
equipment, exercise great care, use insulated tools and test
equipment, and do not work alone.
When fitting option boards, always put the circuit boards
back in the housing with the back-plate securely fastened
before powering up the instrument.
When handling circuit boards, ensure that full anti-static
precautions are observed.
Replace external mains fuse with one of an equivalent type.

Introduction
The Model 4003, 4 digit (9999) LED Universal Temperature
Indicator / Controller is used in applications where temperature
needs to be displayed & controlled.
This DIN 48x96, high accuracy, high-quality panel meter is
designed for accurate measurement & display (in °C, °F or K) of
temperature from thermocouples of Type J, K, N, R, S, T, W5 &
from RTDs such as PT100. Ni100 RTD is available as an option as
well as other thermocouple types. The thermocouple & RTD
signals are accurately linearised by the internal micro-controller.
Options include programmable analog output, 1, 2, 3, or 4 alarm
setpoints, peak / valley hold, RS232/485 communications & more.
The analog output is rangeable from the front pushbuttons.
The instrument meets European Community EMC directive
89/336/EEC and Low Voltage directive 72/23/EEC.
The instrument is designed for non-grounded thermocouple
probes only.

Note 1 : This programming chart is a simplified flowchart for users that have previous experience with this instrument. A programming example is
available in the next few pages to assist new users in understanding this programming chart.
Note 2 : Because this instrument has many options, all possible option menus are shown. Options that are not ordered will not appear in the
programming sequence.
Note 3 : Configuring this instrument requires two steps. (A) Select analog output (option) links (page 6). (B) Program the instrument with this chart.
Note 4 : To enter programming mode, press the menu key for a few seconds (unless the optional keypad lock has been set). Programming mode timeout
is about 20 seconds. If no key is pressed for 20 seconds during programming, the instrument returns to normal display mode.
Note 5 : The selection of the display engineering units (°C, °F, or K) does not automatically change the alarm setpoint units, analog output range etc. If
Hardware overrange. Reduce input signal to reduce saturation.
