1 Introduction
1.1 General information
CLIMO FM is a portable multi functional handheld instrument for measuring air
parameters, sound and light measurments and more.
Instrument features
•All measuring probes can be connected simultaneously.
•Specially designed housing for easy connection of measuring probes directly to
the instrument.
•Optional probe connection with prolongation cable (illuminance, luminance,
sound) or telescopic rod (air velocity, relative humidity, air temperature).
•In built memory for storing/logging measured parameters.
•USB interface for communication with a PC.
•In built rechargeable battery.
•160 x 160 dots graphical LCD with backlight.
•Can be mounted on a tripod.
•Automatic switch-off when not used for 10 minutes.
1.2 Warnings
To ensure a high level of operator's safety while carrying out various
measurements and tests using the instrument, as well as ensuring that the test
equipment remains undamaged, it is necessary to consider the following general
warnings:
The test equipment is intended for use in low voltage environment only !
Service is allowed to be carried out only by an authorised person!
Use only standard or optional test accessories supplied by your distributor !
1.3 Inserting battery cells into the instrument
1. Make sure that the power supply adapter and all probes are disconnect and
the instrument is off.
2. Insert battery cells as shown in
3. Picture 1.1. Insert the cells correctly, otherwise the instrument will not operate
and the batteries could be discharged or damaged.
Picture 1.1 Battery placement

4. Turn the instrument with the display lower than the battery holder (Picture 1.2)
and put the cover on the battery cells.
Picture 1.2: Closing the battery holder
5. Screw the cover on the instrument.
If the instrument is not used for a long period of time remove all battery cells from
the battery holder. The enclosed cells can supply the instrument for approx. 8 hours in
worst case (microclimatic probe connected and measuring). This time is extended if air
velocity measurement is switched off.
Warnings!
•When battery cells have to be replaced, turn off the instrument before
opening battery cover.
•Use only power supply adapter delivered from manufacturer or distributor
of the equipment to avoid possible fire or electric shock.
•Rechargeable NiCd or NiMH battery cells (size AA) are recomended. The
charging time and the operating hours are given for cells with a nominal
capacity of 2100 mAh.
•Do not use standard batteries while power supply adapter is connected,
otherwise they may explode!
•Do not mix battery cells of different types, brands, ages, or charge levels.
•When charging battery for the first time, make sure to charge it for at least
16 hours (24 hours recommended) before switching on the instrument.
•During very long charging (>16 h) in hot (40 °C) environment the battery
holder screw might reach maximum allowed temperature for metal part of
handle. In such environment it is advisable not to touch the battery cover
during or immediately after the charging.

oPower supply and battery charging
Power can be supplied to the instrument from:
•USB input. Recommended means for operating the instrument from an
USB input is for data transfer.
•Battery cells. Recommended means for operating the instrument from
Battery cells is for measuring.
•External power supply. Recommended means for operating the instrument
from an external power supply is for battery charging.
Status of the battery cells is indicated by the battery sign at the upper left corner of the
display (see Picture 2.1). Lines in the battery sign indicates the plenitude of the cells.
If the battery sign is broken it idicates that battery cells are not present in the
instrument.
Battery cells are empty.
Battery cells are full.
If the batery sign is animate from empty to full it indicates the charging of the battery
cells. In build charger monitors the charging process and switch off charging when
battery cells are full.
If the instrument is connected to external power supply the battery cells are charged in
all modes of the instrument. If the instrument is connected to USB master device with
capability of supply the power to the host the battery cells are charged but only in
charging mode (before switch on or after switch off the instrument).
Picture 1.3: Charging mode
1.4 New battery cells or cells unused for a longer period
Unpredictable chemical processes can occur during charging of new battery cells
or cells that were unused for a longer period (more than 3 months). Ni-MH and Ni-Cd
battery cells are affected to capacity degradation (sometimes called as memory effect).
As a result the instrument operation time can be significantly reduced.
Recommended procedure for recovering battery cells:
- Completely charge the battery. (At least 16h with in-built charger)
- Completely discharge the battery. (Can be performed with normal work with the
instrument)

CLIMO FM
8
- Repeat the charge / discharge cycle for at least two times. (Four cycles are
recommended)
Complete discharge / charge cycle is performed automatically for each cell using
external intelligent battery charger.
Notes:
The charger in the instrument is a pack cell charger. This means that the battery
cells are connected in series during the charging. The battery cells have to be
equivalent (same charge condition, same type and age).
One different battery cell can cause an improper charging and incorrect
discharging during normal usage of the entire battery pack (it results in heating of the
battery pack, significantly decreased operation time, reversing polarity of defective
cell,…).
If no improvement is achieved after several charge / discharge cycles, then each
battery cell should be checked (by comparing battery voltages, testing them in a cell
charger, etc). It is very likely that only some of the battery cells are deteriorated.
The effects described above should not be mixed with normal decrease of battery
capacity over time. Battery also loses some capacity when it is repeatedly charged /
discharged. The actual decrease of capacity versus number of charging cycles depends
on battery type and is provided in the technical specification from battery manufacturer.
1.5 Power Supply via Supply Unit
When using the power supply unit A1083 supplied by the manufacturer, the
instrument is immediately operational after switching it on. The storage batteries are
being charged simultaneously. Nominal charging time is 16 hours.
The batteries are always charged when the power supply unit is connected to the
measuring instrument. An integrated protective electrical circuit controls the charging
process and guarantees maximum battery life.
1.6 Periodic calibration
It is essential that the instrument and its probes are calibrated regularly. We
recommend that calibration of the instrument and its probes is carried out once per year
if there are no different recommendations for specific probe. Please contact your
merchant for further information on calibration.
1.7 Service
For repairs under or out of warranty time please contact your merchant for further
information.

3.1.4 Min, Avg, Max, Cur values
Instrument samples current values of measured parameters from all connected
probes approximately once every second. While measuring, the instrument calculates
average and remembers the maximum and the minimum value for each parameter
(physical quantity) during the measurement. Min, Avg and Max values for all probes are
reset at the start of the measurement or when a new probe is connected to the
instrument.
One can switch between Min, Avg, Max and Cur values with the F2 ( Value ) key.
This key switches between Min, Avg, Max and Cur values for all probes connected. It is
also possible to switch only value for one probe with or key. Note that you can
switch between these values also during measurement, and not only after the
measurement is stopped.

In the logger mode the instrument automatically stores all measurements in every
logging interval. This interval is set in Logger settings (described in chapter 5.5.2).
After the measurements are stored, the Min, Max and Avg values are reset and the
instrument starts measuring again for the next logging interval.
Picture 3.8: Logging mode – microclimatic probe connected, logging in progress
Instrument starts logging when the key is pressed. Icon from normal mode
is replaced with icon in logger mode. The number of concluded intervals is displayed
beside the LOG caption. For every logging interval the instrument stores all results that
can be measured until logging is stopped by pressing the key.
The F2 ( Value ) key switches between Min, Avg, Max and Cur values, as in
normal measuring mode. Min, Avg and Max values are cleared at the beginning of
each interval, so they are calculated for each interval separately and not for the whole
duration of logging. Elapsed time in the upper left corner of the status window also
represents elapsed time of each interval and not the whole duration of logging.
Instrument is logging until the key is pressed again or the memory is full.
Instrument can store approximately 4000 values. Table 3.1 shows how long the
instrument is logging if the memory is 100% free (cleared) with different logging
intervals.
Logging interval Estimated logging time
2 s 2 hours 15 min
10 s 11 hours
60 s 2 days 20 hours
10 min 28 days
60 min 170 days

4 Memory management
4.1 Overview
The instrument has enough memory to store approximately 4000 measurement
records. Each such measurement record contains:
•All values (Min, Avg, Max, Cur) of every probe that was connected at the
time of saving the measurement, or at the end of logging interval.
•Some additional information such as the location and time stamp of the
measurement is also stored.
•All values from the sound level measurement (including frequency analysis
data).
Memory is organised in two levels, each level having 100 different locations. First
level represents buildings, and second level represents rooms. Each combination of
both levels represents a memory location under which any number of measurements
can be stored.
The instrument has a single memory buffer for 4000 measurement records,
intended for all measurement modes (normal or logger). When the end of the buffer is
reached the instrument searches from the beginning of the buffer if any measurements
were deleted, and so there is still some free memory space. But the logger requires
coherent free memory space. When it comes to the end of the buffer logging is not
possible anymore and memory data should be downloaded to PC and cleared in order
to enable logging again.
4.2 Saving measurement records
When memory is completely empty (after clearing both memory and logger) every
location is empty and is designated only by number (01-100). After the first
measurement is stored in the desired location, it is renamed from a number to a default
name (Building 01-100 and Location 01-100) or to an optional name that can be written
in special menu (Rename menu described in chapter 4.2.2).
Once the location is renamed (to a default or optional name) it keeps its name until
all measurements on this location are deleted. If all measurements on certain location
are deleted, the location name is also deleted and changed back to a number (01-100).
When the next measurement is saved on this location it is again renamed to a default or
optional name.
