MANUAL CALIBRATION

COMBUSTIBLE GAS CALIBRATION (100% METHANE)

NOTE: 

After calibration of 100% Methane, it is recommended to auto-

zero the unit before use.

From the working display press & hold the TICK/MENU BUTTON (B) 

until the top line reads USER MENU. Press & release the SAVE/ZERO 

BUTTON (C) until the bottom line reads CAL. Press & release the TICK/

MENU BUTTON (B) once, the bottom line will read AUTO CAL.

Press & release SAVE/ZERO BUTTON (C) to scroll until the bottom line 

reads 100%V/V. Apply 100% methane to the instrument. Immediately 

press & release the TICK/MENU BUTTON (B) to start 100% methane 

calibration. 

When the reading is satisfactory, the display will flash  DATA SAVED 

indicating that calibration is complete for that sensor. The date for CAL 

PAST DUE is automatically reset for that sensor as well.

Scroll with the SAVE/ZERO BUTTON (C) if you need to calibrate another 

sensor.  When  finished,  remove  and  shut  off  the  gas  supply.  Press  & 

release the POWER/MUTE BUTTON (A) to return to the working display.
