Your RO 458s combustion analyser measures:
●Carbon Monoxide (CO)
●Carbon Dioxide (CO2)
●Oxygen (O2) if fitted
●Nitric Oxide (NO) if fitted
●Differential Pressure
●Differential temperature
Your RO 458s measures CO2 using KANE’s unique NDIR sensor.
Always use fresh outdoor air to “zero” your analyser during the initial
countdown or when prompted to “ZERO CO2” as indoor CO2 levels are
increased by human activity.
This applies even if your analyser measures O2 instead of CO2 as it is best
practice to use fresh, outdoor air during initial countdown to protect you
from unsafe levels of CO & CO2 possibly present in the room.
Depending on your options these parameters are calculated:
●Oxygen (O2)
●CO/CO2 ratio
● Carbon Monoxide (CO2)
●Combustion Efficiency
●Losses
●Excess Air
●Differential Temperature
Your analyser also measures CO levels in ambient air – useful when a CO
alarm is triggered – & performs a Room CO test for up to 30 minutes.
Your RO 458s has a structured Commissioning Test to help install boilers.
Your RO 458s has a protective rubber cover with magnets for
“hands-free” operation & is supplied with a flue probe with integral
temperature sensor.
Your analyser has a low flow detector to switch off the analyser’s pump if it
detects an over filled water trap.
1 RO 458s Overview
ENGLISH 5
Your RO 458s has a large 6 line display showing data & test results based on
your actions.
Your RO 458s can send test results to our optional KANE IRP-2
infrared printer or KANE’s wireless printer App.
The memory can store up to:
●60 combustion tests
●20 AUX tests
●20 let-by/tightness tests
●20 temperature & pressure tests
● 20 room CO tests
● 20 commissioning Tests
You can personalise 2 lines of 16 characters on your test results header - for
example your company name & telephone number.

Your RO 458s uses rechargeable Nickel Metal Hydride (NiMH)
batteries - using other battery types may void your RO 458s’ warranty.
Warning
Although you can use Alkaline batteries you must not charge your analyser
with Alkaline batteries fitted.
Do not mix NiMH batteries of different capacities or from different
manufacturers – all must be identical.
Turn over your analyser & remove its protective rubber cover. Open the bat-
tery compartment & fit 3 NiMH “AA” rechargeable batteries – check battery
polarity is correct. Replace battery cover & protective rubber cover.
After changing the batteries reset your analyser’s time & date.
Your RO 458s uses a standard Micro USB connector for charging (KANE part
No: USB1).
For best results turn off your analyser then connect your charger – the
charging indicator illuminates & turns off when charging finishes.
Your first charge should be for 8 hours continuously – thereafter NiMH bat-
teries can be topped up at any time, even for short periods.
If the analysers batteries discharge & the analyser enters a ‘low power shut
down’ a 1 hour charge will provide approx 2 hours continuous use.
A
Always dispose of depleted batteries using approved disposal methods that
protect the environment.
