1 GENERAL DESCRIPTION
RIVELGAS plus / EX-PEX plus / Rivelgas Combi are a new family of portable devices for localization of
gas leak and for personal safety. Depending on the device model, they are used either to check pipes, gas
leak detection or for personal safety. It was conceived to be light for portability, and easy to use.
Measured gas concentration is shown on the display. Different scales are available according to the
different models of device: PPM, LEL and VOL.
Alarm threshold can be set by user navigating menu options. Other informations are shown directly
on the display (eg. Battery level, pump status, buzzer status, etc). Power is supplied by NiMH batteries,
which guarantee between 8 to 14 hours of working in nominal conditions, depending on the model (see
datasheet) and can be recharged using the proper battery charger.
The electronics were developed, certified and manufactured according to European Ex directive and
and in compliance with international specifications for safety in environments with explosion risk.
In hazardous environment, the user must take care of the EN 1127-1:2007 (Explosive atmospheres.
Explosion prevention and protection. Basic concepts and methodology ) and the BGR 132 (German
directive :“Vermeidung von elektrostatischer Aufladung”) .
Warning: battery has to be charged in a safe place.

3 FUNCTIONING
3.1 Turning on
In order to turn on the device, press “OK/Start” key until display shows “On”, then release the key.
After switching on the instrument, and before operational use, the instrument performs these check
tests:
Display lights on to test proper functioning.
The word “SOFt” appears on screen, followed by the software release version number (eg.:
“2.0”).
The word “Sn” appears on screen, followed by the instrument’s serial number (eg.: “7734”).
The word “tAr” appears on screen, followed by the month and year of date of last calibration
(eg.: “11” and “2009” meaning November and 2009 respectively).
Multi-process instruments only (mono-process instruments skip to next step): a scrollable
menu appears on screen, with the process abbreviations
“EXPL”, used for personal safety 100%, diffusion mode
“1” and “VOL” symbol, for Rivelgas Plus 1% with pump
“100” and “VOL” symbol, for Rivelgas Plus 100% with pump
“AUTO”, for RIVELGAS plus 1% - 100% with pump
“OFF”, to turn off the instrument without activating any process.
“GAS TYPE” for multigas instrument
To choose the desired process, scroll the menu with “Down” key and then press “Ok”. Note: available
processes may differ through different device models.
The word “CAL” appears on screen, which means that the instrument has started and auto
calibration step. Auto calibration steps include:
oPump powered processes only: pump stops and restart, to check proper pump
functioning.
oMoving dashed lines appear on screen
oLed blinks, to check proper led functioning
oBuzzer beeps, which means end of auto calibration steps.

oIn case the instrument notices sensor malfunctioning, the word “S Er” appears on
screen, and buzzer beeps for 5 seconds, before the instrument switches off.
Device is ready to use and measure is shown.
WARNING: in order to have a correct calibration of the device, it has to be turn on in a place with no
gas.
3.2 Switching process mode
Multi-process instruments only: to switch current instrument process, device must be turned off and
on.
3.3 Turning off
To turn off the instrument, press “OK/Start” key until the end of counter 4 – 3 – 2 – 1 – OFF. If the
key is released before “OFF”, turning off process is stopped.
Device turns off automatically when batteries are discharged, after showing “C-OFF” on display.
3.4 Backlight
To turn on or off backlight, press “OK/Start” key: if the light is off, it will be turned on and vice versa.
3.5 Alarm
After turning on, the instrument measures continuously gas concentrations in medium. When the
measure exceeds alarm threshold, leds flash and buzzer sounds.
The device has two alarm thresholds: one called system alarm (not modifiable by user) and one
called user alarm, set by user. Device sets itself in alarm condition when one of the two alarm thresholds
is reached. When user alarm is exceeded, buzzer can be turned off entering menu and disabling buzzer

(system alarm cannot be turned off). Led alarm will flash independently. When system alarm is reached,
buzzer will sound and it cannot be turned off. Led alarm will flash.
For Ex-Pex 09 model: once measurement exceeds system threshold (generally 2,2%VOL), the display
will show a blinking value of 2,2% (indicating that true measurement may fall above that value), and
buzzer will sound with higher frequency.
3.6 Toxic gases
For devices with toxic gas sensor, the display shows alternatively gas or toxic gas concentrations. If
one of these will exceed alarm threshold, the display shows only the one which is over threshold. If the
other gas will exceed its threshold too, display will show again both gases switching alternatively.
3.7 Autozero
It is possible reset the zero of device only if gas measurement falls under 2000ppm, by pressing
“Up/Menu” key and then “Down” key. “AU-0” is shown on display when applied.
3.8 Save data (OPTIONAL)
On request in the instrument of Rivelgas Family have the ability to save measured values, and
download and store them on PC through appropriate software for later processing.
To save the value seen on display, you have to press “Down” key. “SAUE” word will appear on
display, followed by a number, which represents memory position. This implies the value was
successfully stored. Otherwise, if memory is full, the word “FULL” will appear on display, and the new
value will not be stored. Memory sizes vary between models.
In order to manage device’s memory, you should use the “Data Download Software for Ex-
pex+/Rivelgas+”.
3.9 Menu
To enter the menu, press “Up/Menu” key. A little wrench is shown on left side of display.
