PREFACE
Manual Objectives: This manual shows you how to set up and
use the RTD Panel Thermometer.
This meter is an economical Miniature Temperature Panel
Thermometer featuring a large display with a linearized analog
output that is supplied as a standard feature.
Each of the models* can be converted by the user to display in
degrees Fahrenheit or Celsius between one degree and a tenth
degree resolution.
RTD is an abbreviation for resistive temperature detector. The
meter is designed to measure 100 ohm platinum resistance with
0.00385 temperature coefficient, also known as the European
curve. The RTD will change resistance with a change in
temperature. When using a 2-wire measurement configuration,
lead wire impedance can contribute significant error to the
temperature measurement. When using long lead wires a 3- or
4-wire measurement configuration is recommended.
The meter is available in platinum RTD with 2-, 3-, or 4-wire
connections. All of the models listed in Table 1-1 come standard
with red LEDs, and can be ordered with a green LED display as
an option. The part numbers would then end with Ò-GR".
Also, these meters can be ordered with different power
configurations. Refer to Table 1-3 for available choices.
*Refer to Table 1-1 for the complete listing of models available.

SECTION 3 GETTING STARTED
3.1 Main Board Power Jumpers
Caution: The meter has no power-on switch, so it will
be in operation as soon you apply power.
The meter can be configured to operate on 115VAC or
230VAC by the proper combination of the soldered wire
jumpers that are located on the printed circuit board.
The meter is set at the factory to be powered by the
voltage specified at the time of ordering. The same
transformer is used for either configuration, so all you
need to do is to select the jumpers as described in this
section.
Important: These changes must be performed by a
qualified technician.
Note
☞
To change the Factory preset jumpers, do the following
steps:
Disconnect the power from the unit before proceeding.
1. Remove the main board from the case. Refer to
Disassembly/Assembly Section 3.8.
2. Locate the solder jumpers W1, W2, and W3 (located
near the edge of the main board alongside the
transformer).
3. If your power requirement is 115 V ac, solder jumpers
W1 and W3 should be wired, but jumper W2 should
not. If your power requirement is 230 Vac, solder
jumper W2 should be wired, but jumpers W1 and W3
should not.

SENSOR BREAK PROTECTION:
The proper combination of jumpers on S3 will determine the
direction in which the display and analog output will go if the
RTD sensor breaks (upscale or downscale). The meter is factory
set to upscale break protection. If the sensor breaks, the display
and analog signal will increment (upscale) and the 3 least
significant digits will then go blank. If you require downscale
break protection, refer to Table 3-2 to change the S3 jumper
configuration.

SECTION 6 GLOSSARY
COMMON MODE REJECTION (CMR) - a measure of the affect
of a voltage on the indicated display. It is the ratio of the common
mode voltage to the measured voltage due to a common mode
voltage.
COMMON MODE VOLTAGE (CMV) - the average of the voltage
applied to both wires of a two wire or differential input.
NORMAL MODE REJECTION (NMR) - a measure of the
rejection of unwanted signal due to a voltage applied between
the wires of a two wire or differential input (shown as normal
mode voltage). NMR is the ratio of the normal mode voltage to
the measured voltage due to the normal mode voltage.
TEMPCO - abbreviation for temperature coefficient. It is the
effect of changes in ambient temperature on a particular
parameter, such as zero or span settings.
