4. Measuring Air Volume
 |
4.1 Press the MODE button - AIR VOLUME and ENTER WIDTH (flashing) will be displayed on
LCD.* (fig 5) The M4000 will request the A\C?s outlet width.
4.2 Using Ñ D buttons enter the appropriate measurements in inch.
|
| Fig.5 |
|
 |
4.3 Press ENTER to write width to memory. AIR VOLUME and ENTER LENGTH (flashing) will be
displayed on LCD.* (fig 6)
The M4000 will request the A\C?s outlet length.
4.4 Using Ñ D buttons enter the appropriate measurements in inch. |
| Fig.6 |
|

4.5 Place the probe in front of the units outlet so that the
sensor?s cover is facing the outlet.
Press ENTER, the M4000 will start flashing "WAIT".
"WAIT" will flash for about 20 seconds put the probe on the grill and when "start average" start to flash then move the probe along the unit?s outlet so as to cover the whole area, aim to get an average reading from all available
openings*.
Try to cover all area in less than 10 seconds (fig.8) and repeat again and again for 1 minute
("START AVERAGE" flashing fig.9). |

4.6 If you wish to measure
round grills - after step 4.1 press ENTER button more than 2 sec (long
press) until DIAMETER will be displayed on LCD. (fig.7)
4.7 At the end of one minute the M4000 will beep signaling that measurement time ended. The LCD will display the measured Air Volume in
CFM.(fig.10)

 |
4.8 If you wish to redo this action. Or if you wish to measure few openings press ENTER and return steps 4.2-4.7.
Measure each opening as described up to now and after the last measuring press D and LCD will display the sum of all openings. |

5. Measuring Capacity
| When measuring return air the sensor box should be in the center (no need to move it during measuring) |
 |
5.4 Using the Ñ D buttons enter the outlet?s width (inch) and press ENTER (fig.14 step 3). ENTER LENGTH flashing will be displayed on LCD.
5.5 The M4000 will request the A\C?s outlet length. Using the Ñ D buttons enter the outlet?s length (in inch) (fig.14 step 4, fig.15)
|
| Fig. 15 |
|
 |
5.6 If you wish to measure round grills - after step 5.2 press ENTER button more than 2 sec (long press) until
DIAMETER will be displayed on LCD. (fig.16)
|
| Fig. 16 |
|
 |
5.7 Press ENTER "WAIT" will flash (fig.17) Place the probe in front of the units outlet. Pay attention that the sensor?s
cover is facing the Grill no need to move it. The M4000 is waiting until sensors will be stable with the new temp. and
hum. (about 90 seconds) when "START AVERAGE" will flash (fig. 17) go to 5.8
IMPORTANT:
Read 4.6 (and *) before starting 5.8 |
| Fig. 17 |
|
 |
5.8 Measure for one minute (fig.14 step 5). Make sure you move the probe along the units outlet so as to cover the whole area, aim to get an average reading from all available openings. At the end of this minute the M4000 will beep and the LCD screen will display the result in Btu/h.(fig.18)
Redo measuring outlet air:
5.9 In case you wish to redo this action (return air and the grill size are already in memory) press ENTER and repeat sections 5.4-5.8 above. |
| Fig. 18 |
|
Measuring few outlet's opening:
5.10 When there are several outputs openings but the same return air, press ENTER and repeat sections 5.4 - 5.8 for each one. In this case in section # 5.7 "WAIT" will flash for 20 seconds. Each time a measurement ends the LCD will display the Btu/h for that specific outlet, if you wish to know the total Btu/h of all the outlets measured up to now press D .
