Procedure

Calibrate: (a) with a known source of dry air,
21% or 100% oxygen before using each day
or after 8 hours of continuous use; (b) when
the temperature or pressure of the operating

environment changes; (c) if the oxygen sensor has
been disconnected and reconnected; (d) after the
battery or oxygen sensor has been replaced.

1. Expose the sensor to the calibration gas (refer

to preceding section) for approximately 30 sec-
onds to allow the sensor to stabilize.

2. Continue exposing the sensor to the calibration

gas until the calibration routine is complete.

3. Press and hold the CAL pushbutton for three (3)

seconds to initiate the calibration routine.

4. The LCD displays CAL, top right, during the

calibration routine which takes 15-20 seconds.

5. The software determines from the sensor’s

signal output whether the device is being cali-
brated with 100% or 21% oxygen.

6. If the calibration is successful, the LCD will

display, middle and bottom right, the oxygen
value of the calibration gas and returns to the
SAMPLING mode.

7. Remove the calibration gas and begin sampling.

Calibration Fails
If the calibration fails, the LCD will display ERR as
illustrated.

An unsuccessful calibration can be caused by
several problems with the sensor, calibration
gas or electronics. Dropping the device will
damage the sensor and electronics.

Do not proceed until corrective action is
taken and the device is calibrated success-
fully.


If after three (3) unsuccessful attempts to
calibrate: review section 7 for possible causes and corrective action or

contact Advanced Instruments Inc. at 909-392-6900.


4.5 Mounting
The device can be mounted to a 1” diameter pole or a book shelf using the
optional Dovetail Mounting Kit (P/N A-3675-1) and Dovetail Female Clamp Pole/

Shelf (P/N HRWR-1075) as illustrated below.
The dovetail male bracket, top left and middle, is secured to the rear of the
enclosure with one (1) screw and held in place by registration holes molded
into the enclosure.

The 1” diameter dovetail female, top right, clamp pole/shelf is an optional ac-
cessory commonly found in medical applications.
