Normal / Log
When Normal plotting is selected, the plot area is divided equally.
For Logarithmic plotting, specify Logarithmic Exponential Scale and Plot Position Exponent.
Logarithmic 1
Input signal is converted and plotted in direct logarithmic representation. Specify the lower limit of exponent in ‘Loga-
rithmic Plot Position Exponent’ field within -9 to 8, and how many divisions you wish to have in ‘Exponential Scale’
among 10, 5, 4, 2, and 1.
[Example]
Input range: 1 to 5V
Scale: 1x10
–4
to 1x10
–0
(0.0001 to 1)
Exponential scale: 4
Logarithmic plot position exponent: -4
With 3V input, the engineering unit value equals to 5.0x10
–1
(0.49995).

Plot Position for 3V input
Engineering unit scale
The lower plot range value equals to 1x10
–4
, the upper value equals to 1x10
0
. 3V input, 0.5 in the engineering range
equals to 5.0x10
–1
, which is plotted as shown above.
Logarithmic 2
Input signal is converted and only the exponential scale is plotted. Specify the lower limit of exponent in ‘Logarithmic
Plot Position Exponent’ field within -9 to 8, and how many divisions you wish to have in ‘Exponential Scale’ among 10,
5, 4, 2, and 1.
[Example]
Input range: 1 to 5V
Scale: 1x10
–4
to 1x10
–0
(0.0001 to 1)
Exponential scale: 4
Logarithmic plot position exponent: -4
With 3V input, the engineering unit value equals to 1x10

Plot Position for 3V input
Engineering unit scale
The lower plot range value, the same as in the case of Logarithmic 1, equals to 1x10
–4
, the upper value equals to
1x10
0
. Only the part of exponential scale (-2) of 3V input, 1x10
–1
, is plotted as shown above.
CJC (Cold Junction Compensation) SW
Specify this setting for thermocouple input.
OFF
Disable CJC
ON
Enable CJC
Burnout type
Select ‘No Burnout’ to minimize the measuring errors caused by the sensor/wire resistance and the burnout sensing
current.
With RTD input, the signal may go transiently to the opposite direction from the burnout setting.
With DC input, the burnout setting is ignored and the burnout sensing current is cancelled.
None
No burnout

Upscale burnout
Downscale
