measuring principle: Capillary controlled concentration sensor
Alarm conditions: TWA alarm, STEL alarm, low alarm, high alarm,
multi-gas alarm, over limit (OL) alarm, low battery alarm, confidence
beep, automatic deactivation alarm, pump alarm
Audible alarm: 95 dB+ at 30 cm variable pulsed beeper with full battery
charge
Visual alarm: Red light-emitting diodes (LEDs)
Display: Alphanumeric liquid crystal display (LCD)
Backlight: Activates upon startup and when the pushbutton is pressed;
deactivates after 10 seconds. Activates during an alarm condition and
remains lit until alarm ceases
Self-test: Initiated during activation, self-test runs continuously while
detector is operational
Calibration: Automatic zero and automatic span
User field options: Startup message, lockout on self-test error, safe
mode, confidence beep, latching alarm, force calibration, cal IR lock,
force bump, location logging, force block test, set datalog interval, set
confidence interval, language selection.
Sensor options: Sensor enable/disable, set span concentration values,
set calibration interval, set bump interval, set alarm setpoints, set STEL
interval, set TWA period, auto zero at startup enable/disable, 5% over-
span, low alarm acknowledge, oxygen measurement, and combustible
gas measurement
Maximum hose length for sampling: 75 ft (22 m)
Maximum hose length for calibration: 3 ft (0.9 m)
Battery operating time: One rechargeable lithium polymer battery at
20°C provides 13 hours operating runtime
Year of manufacture: The detector’s year of manufacture is determined
from the serial number. The first and second number after the first two
letters determines the year of manufacture.
Example: MA110
-001000 = 2010 year of manufacture
