 Do not try to repair the analyzer or adjust its optical units
and electronic boards by yourself, except for cases stipulated
in troubleshooting section (Appendix 1).
 Call an authorized agent or certified service engineer in
the following cases:
 If the analyzer does not operate properly or its pa-
rameters have noticeably deteriorated.
 If the analyzer has fallen down or if its case is dam-
aged.
 If there has been ingress of any liquid inside the ana-
lyzer.
 If you hear unusual sounds or sense unusual smell
coming from the analyzer.
 Keep the analyzer at a minimum distance of 1 meter from
heating devices and heat sources. Do not transport analyzer in
the boot of your car.
 Do not forget to switch the analyzer off when the working
day is over and to disconnect the power supply unit from the
mains if the analyzer is not used for more than 6 hours.
 Never work without sorption and dust filters.
 The analyzer should be switched off before any mainte-
nance operations.
 When measuring mercury concentration, it is necessary
to follow instructions and documents stating safety regulations
for operation in chemical laboratories and safety rules for oper-
ation with electric appliances.
Observe the following rules during any transportation of the
device, as well as when performing measurements from a moving
vehicle (car, helicopter, etc.):
 To avoid strong vibration effects, do not place the device
on a hard surface (baggage compartment, floor of a vehicle,
etc.).

Operation manual RA-915M В0100-00-00-00-00 OM
IV
 Place the device on shock-insulated surfaces (a seat,
damping support, etc.).
 Secure the device on a working surface to prevent its fall
or incidental contact with other objects.
Observe the following safety precautions during outdoor opera-
tion:
 Do not work in rainy or foggy weather and avoid precipita-
tion ingress inside the analyzer.
 Do not work in dusty ambient air.
 Staff members permitted to operate the device are rec-
ommended to undergo training at the supplier’s premises or at
a regional service centre.

1 Introduction
1.1 General description
The RA-915М Analyzer is intended for measuring mercury va-
pour concentration in the ambient air and in the air of residential
quarters and production areas as well as in natural gas and in facto-
ry smokestack emissions.
The analyzer can be used for on-stream measuring of mercury
vapour concentration in the air both in a stationary mode and for con-
tinuous survey from vehicles (car, helicopter, boat).
The analyzer is a useful tool in industrial hygiene, ecological
monitoring, technological process control and scientific research.
The analyzer and its attachments constitute the system, which
enables the determination of mercury content in potable, natural and
waste water samples, soils, foodstuff and feed stocks, biological
samples, oil and its processing products in accordance with estab-
lished techniques.
Read this manual carefully before starting operation with the analyz-
er.

2.1 Pre-operational Procedures and Setup
2.1.1 Unpacking and Installation
Unpack the analyzer in the following order:
Use a sharp tool to cut the packing straps and carefully open
the transportation box;
Remove the foam frame to uncover the analyzer, documen-
tation and analyzer accessories;
Take the analyzer out of the transportation box and put it on
a table;
Take out the documentation;
Take out the accessories.
Make sure that the package with the analyzer is stored indoors for at
least ten hours after the transportation at temperatures below 0C and then
start unpacking the analyzer.
For transportation the analyzer should be packed in the reverse or-
der.
Before starting the operation with the analyzer make sure that there
are no external damages of the analyzer and its accessories. Check if the
delivery set is complete in accordance with the enclosed packing list.
In the case of any inconsistency please contact your Supplier

2.1.2 Analyzer installation and starting up
Place the analyzer horizontally on a working surface so that the dis-
play and control unit is on the top.
Switch on the analyzer by pressing the On/Off button (pos.5, Fig.
1-5) and hold it down for 1-2 seconds (to switch the analyzer off press the
On/Off button and hold it down for 4-5 seconds). The splash screen that
contains the model name, the manufacturer’s name, the serial number,
software versions and the current date and time will appear on the display
(Fig. 2-1).
Fig. 2-1 - Splash screen
Check the battery charge level in case of the stand-alone use. The
indicator located in the right top corner of the display shows the current
charge level of the battery. If necessary, charge the battery as described in
section 2.1.3.
Press the Ent button to enter the Main menu (see Fig. 2-2).
If you only need to recharge the battery and/or to download the
monitoring data from the analyzer to the computer, it is recom-
mended not to ignite the lamp to extend its lifetime.
