ozone meter OZ-ONE

Cross sensitivities

Due to the construction of the electro chemical sensor, the

device also reacts to other gases than ozone. Besides, a high

humidity level (e.g. by blowing into the measuring probe) can

falsify the result. For this reason, always make sure that no

other gases influence the measurement and that the measuring

probe is not exposed to sources of high humidity when you

measure the ozone concentration.

Displaying DP and WBvalues

The ozone concentration is always displayed by the

measurement value display for ozone concentration(16) of the

device.

Further measured values that can be indicated are the dew

point temperatureDP and the wet-bulb temperatureWB.

Please proceed as follows to have these values displayed by the

device:

1. Repeatedly press the MODE button(8) until the desired

measured value is displayed.

Setting the HOLDfunction

1. Press the HOLD button(10).

ð The current values for the ozone concentration, relative

humidity level and ambient temperature will be held.

2. Press the HOLD button(10) again.

ð The display again indicates the current measured

values.

Setting the MAX/ MINfunction

You can view the highest or lowest value for the ozone

concentration from the current measuring interval.

To do so, please proceed as follows:

1. Briefly press the MAX/MIN button(2).

ð The MAX indication appears on the display(11) in the

measuring mode indication(14).

ð The display now indicates the highest ozone

concentration measured since the device was switched

on in the selected measuring mode.

2. Press the MAX/MIN button(2) again.

ð The MIN indication appears on the display(11) in the

measuring mode indication(14).

ð The display now indicates the lowest ozone

concentration measured since the device was switched

on in the selected measuring mode.

3. Press the MAX/MIN button(2) three times in total to return

to the normal measuring mode.

ð The display(11) again indicates the current measured

value for the ozone concentration.

Resetting the MAX/MINvalues

The MAX/MIN values of the current measuring interval can be

reset. To do so, please proceed as follows:

1. When MAX or MINindication appears on the display, press

and hold the HOLD button(10) for approx. 3seconds.

ð "CLr" will be displayed. The MAX/MIN values of the

current measuring interval will be reset and the device

automatically returns to the normal measuring mode.

Displaying the time-weighted average of the ozone

concentration

The time-weighted averageTWA indicates the average value of

the ozone concentration measured over a period of eight hours.

If the device was in operation for less than eight hours, the

average value will be calculated based on the time span since

the last switch-on.

Please proceed as follows to have the time-weighted average

valueTWA displayed by the device:

1. Repeatedly press the MAX/MIN button(2) until TWA is

indicated in the measuring mode indication(14) of the

display(11).

ð The device indicates the time-weighted averageTWA

for the measured ozone concentration.

Displaying the short-term exposure limit for the ozone

concentration

The short-term exposure limitSTEL indicates the average value

of the ozone concentration measured over a period of

15minutes. If the device was in operation for less than

15minutes, the short-term exposure limitSTEL will be

calculated based on the time span since the last switch-on.

Please proceed as follows to have the short-term exposure

limitSTEL displayed by the device:

1. Repeatedly press the MAX/MIN button(2) until STEL is

indicated in the measuring mode indication(14) of the

display(11).

ð The device indicates the short-term exposure limitSTEL

for the measured ozone concentration.

Changing the unit for the ozone concentration ppm/ μg/m

The device can display the ozone concentration in either ppm or

μg/m

. To change the units at the device, please proceed as

follows:

1. Press and hold the UNIT button(3) for approx. 3seconds to

change the unit.

ð The currently selected unit ppm or μg/m

will be

indicated in the unit indication for the ozone

concentration(15) of the display(11).
