SMARTMETER
PORTABLE TEMPERATURE METER - INSTRUCTIONS MANUAL –V1.0x
1INTRODUCTION
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.
1.1 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.

Only two input terminals are used to connect thermocouples. Input
terminals have different size holes, which prevent inappropriate
installations.

4OPERATION
The meter features two input channels. Channel readouts are
updated two times per second. Channel 1 readouts are shown in the
largest digits and channel 2 readouts are shown in the smallest digits,
as Figure 07 shows. Channel 02 can be turned-off by operator.

4.1 TURNING THE METER ON/OFF
Press to turn on the meter. To turn off, press for 3 seconds.
The meter basic configuration is factory set, so it can be immediately
used with the sensor provided. Factory configuration is: two enabled
channels, K-type sensor, one decimal space, zero offset, sound
alarm not enabled, auto power off after five minutes, temperature unit
in degrees Celsius, 60 Hz filter and channels 1 and 2 for special
functions.
4.2 FIRST READOUTS
Insert the sensor provided with the meter in the terminals of the
required channel and take the sensor leads to the measurement
location. Check the indication displayed.
Use the keys to find special functions the meter offers. When using
other sensors, check if factory setup is still compliant. If not, access
the configuration cycle and change settings.

measured within an interval. An indicator of such condition is
displayed in the meter. It is activated by pressing key
AVG
MAX MIN
.To
resume the meter operation, press key
AVG
MAX MIN
again.
MAX FUNCTION
It allows the user to retrieve the maximum temperature value
measured within an interval. An indicator of such condition is
displayed in the meter. It is activated by pressing key
AVG
MAX MIN

again.
AVG FUNCTION (average)
It displays the average temperature value measured within an
interval. An indicator of such condition is displayed in the meter. It is
activated by pressing key
AVG
MAX MIN
.To resume the meter operation,
press key
AVG
MAX MIN
again.
Notes: Functions MIN, MAX and AVG are accessed via key
AVG
MAX MIN
.
Values displayed are the ones acquired from the start of an interval of
measurements. The interval starts after a RESET action.To reset the
meter, press and hold key
AVG
MAX MIN
for more than 10 seconds. When
reset button is pressed, MIN, MAX and AVG values are erased and a
new interval starts.
RELAT FUNCTION (relative)
When enabled, it will void the measured values and starts to indicate
variations from such zeroed values. An indicator of such condition is
displayed in the meter. It is activated by pressing key
RELAT
.To
resume the meter operation, press key
RELAT
again.
T1 –T2 FUNCTION
When enabled, it displays the highest value corresponding to the
difference between the value measured through channel 1 and the
value measured through channel 2. The indication corresponding to
channel 2 is not changed. An indicator of such condition is displayed
in the meter. It is activated by pressing key
T1 –T2
.To resume the
meter operation, press key
T1 –T2
again.
Note: This function is only enabled when both channels are enabled
and operating.
ALARMS
The meter has an audible alarm (BEEP) that can inform the operator
about an alarm condition. In each channel there can be two indication
values, when they are reached the audible alarm is triggered. A
visual indicator is also displayed in the meter when the indication is
under an alarm condition.
LOW BATTERY INDICATOR
A low meter indicator is displayed warning that the battery should be
replaced.
SET UP
To set up the meter, the user must access the Alarm and Meter Set
up cycles, where a series of parameters must be defined.
ALARM CYCLE
In the alarm cycle you find the setpoints parameters of the meter
alarms. Press
SET
to access this cycle. The meter displays spk.1,
the first parameter of the cycle. To access the remaining parameters
of this cycle, press

Determines a temperature value in channel 1 that when exceeded
downwards triggers the meter alarm (BEEP). When the alarm is
triggered, the indication ALARM is displayed in the meter.
spk.2 (Highest setpoint of channel 2)
Determines a temperature value in channel 2 that when exceeded
upwards triggers the meter alarm (BEEP). When the alarm is
triggered, the indication ALARM is displayed in the meter.
spk1.2 (Lowest setpoint of channel 2)
Determines a temperature value in channel 2 that when exceeded
downwards triggers the meter alarm (BEEP). When the alarm is
triggered, the indication ALARM is displayed in the meter.

it may be required to press or several times.
5CALIBRATION
The meter is factory calibrated, and recalibration by non-experienced
professionals is not recommended. If required, calibration must be
performed by expert professionals, who must proceed as it follows:
a) Configure the type of input to be calibrated: K thermocouple or
Pt100 or 0-50 mV.
Note: By calibrating K thermocouple, all the remaining
thermocouples will be automatically calibrated. Pt100 and 0-50
mV required their own calibration processes.
b) Access the Calibration cycle.
c) Apply to the input channel a signal corresponding to a known
indication, and slightly over the lowest limit of input type
indication.
d) To access parameter L(.(1 (or L(.(2). Use keys and
until the meter indicates the value corresponding to the applied
signal.
e) Apply to the input channel a signal corresponding to a known
indication, and slightly below the highest limit of input type
indication.
f) Access parameter k(.(1 (or k(.(2. Use keys and until
the meter indicates the value corresponding to the applied signal.
g) Repeat cto funtil no adjustment is further required.
Note: While calibrating the meter, observe if the Pt100 excitation
current required by the calibrator used is compliant to the Pt100
excitation current used in this instrument. 0.165 mA.
