SMARTMETER
PORTABLE TEMPERATURE METER - INSTRUCTIONS MANUAL – V1.0x
1
INTRODUCTION
SmartMeter is a portable temperature meter with high-contrast LCD.
The Smart Meter housing enables industrial environment or bench-
top operation and provides a belt carrying fixture. It supports 2
temperature sensors with independent and concurrent display of
measured values. It provides the capability of reading 0-50 mV
electric signals with configurable indication scale.
Difference between channels, relative measure, minimum, maximum
and average values, hold and alarm functions are also available. It
also features an auto power off resource in case the device is idle, in
order to extend battery life.
The device is supplied with a K-type thermocouple with 1.5 m cable.

UNPACKING
The meter is supplied in proper packaging that offers suitable
protection during transit and storage. Unpack with care. Upon
delivery, make sure that there is no damage to the instrument, and
that there are no missing items.
Within packaging, you should find, besides the manual, the meter
and a K-type thermocouple sensor.

CONNECTIONS
Female input connectors suitable for RTD / TC compensated
connectors, as shown below.
Figure 01
— Meter supported connectors
Only two input terminals are used to connect thermocouples. Input
terminals have different size holes, which prevent inappropriate
installations.

The Pt100 internal connections should be made as shown in figure
below.
