All specifications stated in this manual may change without notice.
(1) Require use of Sample Draw System.
(2) Recommended use of Sample Draw System, for enhanced sensitivity and speed of response.
*0 = 4mA = 100mV, upper point = 20mA = 500 mV
**Gas not available in cylinders, a gas generator must be used

: If a non-standard range and/or a non-standard calibration gas are used, utilize the equations in Section 3.0 to determine
voltage readings.
