Note highlights important information on using the product.
Product Related Safety
Precautions
The Hand-Held Carbon Dioxide Meter GM70 delivered to
you has been tested for safety and approved as shipped from
the factory. Note the following precautions:
Do not modify the unit. Improper modification can damage
the product or lead to malfunction.
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent
damage to electronic circuits. Vaisala products are

However, it is possible to damage the product by delivering
electrostatic discharges when touching, removing, or
inserting any objects inside the equipment housing.
To make sure you are not delivering high static voltages
yourself:
8 ______________________________________________________ M010139EN-D
Chapter 1 ___________________________________________ General Information
- Handle ESD sensitive components on a properly
grounded and protected ESD workbench. When this is
not possible, ground yourself to the equipment chassis
before touching the boards. Ground yourself with a wrist
strap and a resistive connection cord. When neither of the
above is possible, touch a conductive part of the
equipment chassis with your other hand before touching
the boards.
- Always hold the boards by the edges and avoid touching
the component contacts.
Recycling
Recycle all applicable material.
Dispose of batteries and the unit according to statutory
regulations. Do not dispose of with regular household
refuse.

Tool for Adjustments
For adjusting the GMT220 series transmitters the GM70
needs only the probes. GM70 adjusts and stores the
adjusting information to the nonvolatile memory of the
probes. This enables true interchangeability of the probes.

CHAPTER 3
PREPARATIONS BEFORE USE
Recharging the Batteries
1. If using alkalines, unscrew the back plate of the
indicator and insert the alkalines. If the GM70 is
ordered with a rechargeable battery pack, the battery
pack is already in place as shipped from the factory.
2. Recharge the battery pack as follows: Plug in recharger
to the recharger connector of the indicator and connect
the recharger to wall socket. A battery symbol in
corner of display starts to roll.
- It is not recommended to use the GM70 during the
first recharging. Later on the GM70 can be used
while recharging.
- Duration of recharging depends on the charge level
of the battery pack being 4 hours typical. The
recommended first recharging time is 6 hours.
3. The battery pack is full when the battery symbol stops
to roll.
4. Disconnect the recharger.

Chapter 4 ______________________________________ Measuring Carbon Dioxide
CHAPTER 4
MEASURING CARBON DIOXIDE
The results of carbon dioxide measurements are affected by
the air pressure and the temperature of the measurement
conditions. For achieving the most accurate measurements
in high altitudes where the barometric pressure is clearly
lower than in the sea level, the actual atmospheric pressure
value should be set to the GM70. The acceptable pressure
value range is 700...1300 hPa.
NOTE
Before measurements ensure that the air pressure and
temperature settings are correct. Set the correct settings as
instructed on page
27.
Taking Measurements (Diffusion Sampling)
See Chapter 3 Preparations Before Use on page 17 if you
start the GM70 for the first time, otherwise follow the
instructions below:
1. Connect the probe cable to the MI70 indicator's
connector port.
2. Press

Taking Measurements (Pump Aspirated Sampling)
See Chapter 3 Preparations Before Use on page 17 if you
start the GM70 for the first time, otherwise follow the
instructions below:
1. Connect one end of the sampling tube to the gas inlet
(marked with IN), in case of using a tube.
2. Connect the black cable of the GM70PUMP to the
MI70 indicator's connector port.
3. Plug in the recharger connector of the MI70 and
connect the recharger to wall socket.
4. Connect the GM220 probe to the probe connector of
the GM70PUMP.
5. Insert the probe in the measuring chamber. Note that to
have a tight installation, the two O-rings on the
opening of the measuring chamber should not match
together with the filter edge or the tapes on the probe
(see figure). When operating the pump, especially
when taking a sample from hot and humid conditions
into room temperature, take care that no condensation
forms on the probe.

The following number refers to
Figure 2 above:

surface to have a tight connection!
Only one pump aspirated system can be connected to the
MI70 at a time.
When using the pump aspirated system it is recommended
to power the system by using the recharger connected to a
wall socket.
The battery indicator of the MI70 display does NOT show
the actual recharge level when the pump is in operation.
