Docking.
When docked, instruments that are supported by iNet® Control or DSSAC (Docking Station Software
Admin Console) will be maintained for all scheduled bump tests and calibrations, synchronized for any
changes to settings, and upgraded for improvements from Industrial Scientific.
Other Maintenance.
The time-weighted average (TWA), short-term exposure limit (STEL), and peak readings can each be
"cleared". When any summary reading is cleared, its value is reset to zero and its time-related setting is
also reset to zero.

Procedure
Recommended minimum frequency
Settings
Before first use, when an installed sensor is replaced, and as needed.
Calibration
a
Before first use and monthly thereafter.
Bump test
b
Before first use and prior to each day’s use thereafter.
Self-test
c
As needed.
a
Between regular calibrations, Industrial Scientific also recommends a calibration be performed immediately following each of these incidences:
the unit falls, is dropped, or experiences another significant impact; is exposed to water; fails a bump test; or has been exposed to an over-
range (positive or negative) gas concentration. A calibration is also recommended after the installation of a new (or replacement) sensor.
b
If conditions do not permit daily bump testing, the procedure may be done less frequently based on instrument use, potential exposure to gas,
and environmental conditions as determined by company policy and local regulatory standards.
b
When redundant sensors are operating on DualSense® technology, bump testing these sensors may be done less frequently based on
company safety policy.
c
The instrument performs a self-test during power on. For an instrument that is set for always-on, the instrument will automatically perform a
self-test every 24 hours. The self-test can also be completed on demand by the instrument user.
Note:
The use of calibration gases not provided by Industrial Scientific may void product warranties and limit potential liability claims.
First Use
To prepare the Ventis Pro Series instrument for first use, qualified personnel should ensure the following
are completed:
Charge the battery.
Review instrument settings and adjust them as needed.
Calibrate the instrument.
Complete a bump test.
Wearing the Instrument
Based on the U.S. Department of Labor's Occupational Safety and Health Administration (OSHA) definition
of the breathing zone, it is recommended that the instrument be worn within a 25.4 cm (10") radius of the
nose and mouth. Refer to OSHA and to other agencies or groups as needed for additional information.
LENS™ Wireless Considerations
LENS™ Wireless (Linked Equipment Network for Safety) from Industrial Scientific is used to form wirelessly
connected instrument "groups". It allows the communication of gas readings, alarms, and other data among
LENS-connected "peer" instruments.
