Innova Series Operator’s Manual
Once gas is detected a countdown is initiated. During this single beep
countdown the user should visually verify the sensors are responding
correctly.
NOTE
Bump test peak readings are recorded. Events are recorded as
“BUMP
TEST COMPLETE”
if the Innova detected gas, and
“BUMP TEST
ABORTED”
if the Innova did not detect gas.
A
“BUMP TEST COMPLETE”
message will be displayed. Then the
screen will alternate between
“REMOVE GAS”
and the gas readings.
6. Remove the tubing from the probe.
Once the instrument detects that the gas has been removed the screen
display an
“ALARMS SILENCED”
message. The alarms will be
silenced for a blind 30 second count.
After the 30 second count has elapsed an
“ALARMS ACTIVE”
message will display briefly, audible alarms will be enabled and the
Innova will return to the normal operating mode.
NOTE
If the Innova does not respond properly during the bump test, follow the
instructions in Chapter 5, Calibration, or Chapter 6, Troubleshooting
sections of this manual.
NOTE
For instruments having a toxic sensor other than CO or H
2
S, calibration
gases are only available in single-gas cylinders. Therefore a multi-step
bump process has been programmed into the bump test routine. First,
the standard sensors are bumped using a multi-gas mixture. Then the
first Toxic sensor is bumped using a single-gas cylinder and repeated if
your unit has a second toxic sensor.
WARNING
Avoid using a gas mixture containing H
2
S for bump testing an
instrument with Cl

, NH

, NO

or PH

sensors.
