6. Special Functions
6.1 Automatic Switch Off
In order to increase the battery life time the instrument is provided with a Standby Mode.
In case no key has been touched for 30 minutes and the instrument is not in a measuring
mode the display back light and the gas pump will be switched off. If any key is touched
the MSI EM200-E automatically switches on again.
The information "Standby" is shown in the display. After 30 minutes of standby time the in-
strument will be switched off completely.
6.2 Protection of the CO-Sensor
The instrument is equipped with a special function protecting the sensors from getting
harmed by too high CO-concentrations.
During the first contact with the exhaust gas the MSI EM200-E automatically assesses how
fast the concentration rises and recognises if the measuring range (8,000 ppm) will be ex-
ceeded.
The pump is switched off and the display demands to draw in fresh air.
With pushing a button you may start the pump again. If the concentration has been very
high, it is possible that the concentration at the sensor is still > 8,000 ppm. In this case the
CO value is replaced by dashes.
Wait until the concentration is < 1,000 ppm before you start measuring again.
6.3 Online Data Transfer
The MSI EM200-E possesses an online data transfer feature. If “Emission Test” is activated,
all measured data are transferred to the USB interface of the instrument.
With the PC program DERAS from Dräger MSI all measured values may be shown online
(numeric or graphic) on a PCs monitor. The PC program allows additional storing of the
values in a chosen interval. The stored data may be printed in numeric or graphic charts.
With the PC program DEXAS from Dräger MSI all stored values may be transferred to Excel.
