Specifications subject to change.
WARNINGS
To ensure safe operation and service of the meter, follow these
instructions. CARBON MONOXIDE IS LIFE-THREATENING EVEN AT
RELATIVELY LOW CONCENTRATIONS. Failure to observe these
warnings can result in severe injury or death.
• Read the instructions to ensure safe operation.
• Initial calibration should be performed in an area known to
be free of carbon monoxide. Calibration in an area containing
carbon monoxide will result in incorrect calibration and lower
than actual readings.
• Meter is NOT intended as personal protection equipment (PPE).
• Meter is NOT insulated. Avoid contact with areas where
energized conductive elements may be present. Shut off power
to the area before starting measurements.
• Always wear approved eye protection.

A long press of the Power Button will power on and off the meter.
During the setup process, a short press will exit the current screen.
Meter will automatically power-off after 20 minutes of non-activity.
TEMP / ^
5
Press the TEMP Button to enter temperature measurement mode.
Readings wil be in Celsius (°C ) by default. Press TEMP Button again
to switch to Farenheit (°F ). In Set-Up mode, the TEMP Button is used
to increase parameter values.
BACKLIGHT /
6
When powered on, the backlight is off by default. Press the Backlight
Button to turn the backlight on or off. Backlight will remain on until it
or the meter itself is turned off. In Set-Up mode, the Backlight Button
is used to decrease parameter values.
MAX/AVG

Pressing the MAX/AVG Button will display the maximum
concentration value measures since powering-on, pressing again will
display the average (AVG) value. A long press will clear all data.
MUTE
8
A short press of the Mute Button will stop the active alarm for 3
minutes. A long press will reset the alarm.
HOLD
9
Press the HOLD Button to hold the current measurement on the
display. Press again to return to live measurement mode.
SET

Press the SET Button to enter Sensor Self-Test mode. For calibration,
short-press to choose parameters and long-press to save current
parameter values.
WARNING INDICATOR LIGHT

BEFORE USING THIS METER
Carbon Monoxide (CO) is a colorless, odorless, flavorless gas that
is life-threatening even at relatively low concentrations. Before using
this meter, read and understand the information in the chart below
pertaining to CO concentration levels.
OPERATING INSTRUCTIONS
TESTING
1. Long-press the power button to power-on the meter; the ZeroSetting icon H will flash. It is at this time that the zero-point is
set, so ensure to power-on in an area free of carbon monoxide.
2. After powering-on, press the SET Button 10 to perform a
3-minute diagnostic self-test. It is strongly suggested to perform
this procedure once for every 24 hours of use.
3. Place the meter into the area to monitor. The response time to
reach T90 (90% of reading) is 1 minute.
• At CO concentration levels above the A1 Low Alarm limit of
35 ppm (TWA), the buzzer will sound, the light will flash at a
frequency of 1Hz, and the LO icon F will appear on the display.
• At concentration levels above the A2 High Alarm limit of 200 ppm,
the buzzer will sound, the light will flash at a frequency of 2Hz and
the HI icon F will appear on the display.
• The STEL icon K will appear when an average of 200 ppm
exposure is present for 15 minutes.
Once you have confirmed the alarm conditions, press the MUTE
button to stop audible alarm for approx. 3 minutes. Press again to
reactivate the audible alarm immediately.

MAINTENANCE
CALIBRATION
For best results, calibration should be performed by a professional in an
environment with a known concentration of carbon monoxide.
SENSOR REPLACEMENT
When the FAULT icon L appears on the display, the
electrochemical
sensor must be replaced.
This CANNOT be done by the user;
please
contact Klein Tools for more information.
BATTERY REPLACEMENT
When the indicator is displayed,
the batteries must be replaced.
