Mx+B Scaling
The menu for setting Mx+B scaling values takes you through the following steps:
 
Set the M value (sign and number).
 
Set the decimal point location for the M value.
 
Set the multiplier for the M value (m, x1, k, M).
 
Set the B value (sign and number).
 
Set the decimal point location for the B value.
 
Set the multiplier for the B value (m, x1, k, M).
Use 
G, D, H and J to cycle through the selections at each step. Then press
EE to accept your choice and advance to the next step.
For example, to set an M value of 1.8 and a B value of 32 for channel 7, do the
following:
1.
 
Select channel 7 by pressing 
G or D.
2.
 
Press 
B to begin Mx+B scaling setting for channel 7.
3.
 
Use the arrow buttons to select "+18000". Press 
H or J to move between digits.
Press 
G or D to select the value for each digit. (Ignore the decimal point). Press
EE to accept these digits.
4.
 
Use the arrow buttons to select the decimal point position ("+1.8000"). Then press
E to accept this position.
5.
 
Next, use the arrow buttons again to select the multiplier ("x1"). Press 
E to
accept this multiplier.
6.
 
Use the arrow buttons to select +00320. Then press 
EE.
7.
 
Use the arrow buttons to select the decimal point position ("+0032.0"). Then press
E to accept this position.
8.
 
Next, use the arrow buttons again to select the multiplier ("x1").Press 
E to
accept this multiplier as the multiplier for the B value.
Mx+B scaling is now set at 1.8x+32 for channel 7.
Pressing 
D while partway through setting the M value undoes all changes entered thus
far, returning the instrument to Inactive Mode. Pressing 
D while partway through
setting the B value cancels entries made thus far for the B value, but does not affect any
changes already made to the M value.
Setting the Scan Interval
Press 
I to set the scan interval. The latest value appears on the right display. The
format of the display is H:MM:SS. Use 
J and H to move between digits. Use G and
D to select the new value for a digit. Values ranging from 0:00:00 to 9:99:99 are
allowed. Press 
E to accept the displayed value.
Set the interval to 0:00:00 for continuous scanning. If you set the interval to a value
shorter than the time required to measure all channels, scanning effectively becomes
continuous.
