Handle the probe carefully. Strong impact or falling can damage the

probe.

If you need to disconnect the probe, first press POWER ON/OFF button to

turn the indicator OFF. This ensures that all settings and data are saved

properly.

Taking Measurements (Pump Aspirated

Sampling With GM70PUMP)

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 2 on page 21). 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.

6. Install the other end of the sampling tube to the sampling location.

7. Turn on the MI70 indicator by pressing the button.

8. Turn on the GM70PUMP.

9. The basic display opens.

10. Wait for a few minutes to get a stabilized reading. For the most

accurate readings wait for 15 minutes to reach the full operating

state of the GM70.
