Max Iteration
for Voltage
C8 1 +10
Number of attempts to reach the
target value (Calibration Voltage
entry) within the programmed
tolerance.
If maximum number of
iterations to be tried for
obtaining the target value of
voltage within the set
tolerance (at C4) is to be
reduced to 5, then enter:
>)C8=+5<CR>
Max Iteration
for Current
C9 1 +10
Number of attempts to reach the
target value (Calibration Voltage
entry) within the programmed
tolerance.
If maximum number of
iterations to be tried for
obtaining the target value of
power within the set
tolerance (at C5) is to be
reduced to 5, then enter:
>)C9=+5<CR>
Tolerance on
Watts
CA mW +0.010
Measured value to fall within this
set tolerance of the target value
(Calibration Voltage multiplied by
the calibration current entries) for
the calibration to be complete.
If the tolerance to the target
power is desired to be more
coarse, to within 0.1W, the
user can enter the
following:
>)CA=+0.100<CR>
Average
Count for
Watts
CB 1 +3
Measured value to fall within this
set tolerance of the target value
(Calibration Voltage multiplied by
the calibration current entries) for
the calibration to be complete.
If the amount of averaging
for the power measurement
is desired to increase to 10
enter the following:
>)CB=+10<CR>
Max Iteration
for Watts
CC 1 +10
Number of attempts to reach the
target value (Calibration Voltage
multiplied by the calibration
current entries) within the
programmed tolerance.
If maximum number of
iterations to be tried for
obtaining the target value of
power within the set
tolerance (at CA) is to be
reduced to 5, then enter:
>)CC=+5<CR>
Calibration
WRATE
CD 1 +20732
Entry for WRATE during the
calibration step only. After
calibration, WRATE returns to the
value entered in ]0F.
Calibration
Temperature
CE
0.1°C
+22.0
Target nominal temperature for
calibration.
If the user desires the
target nominal temperature
to be 25°C, then set as
follows:
>)CE=+25.0<CR>
Calibration
Watts
CF mW 120.000 Target Watts used for calibration.
If the target Watts for
calibration is 240, enter the
following:
>)CF=+240.000<CR>
Temp Alarm
Min Threshold
D0 0.1°C +0.0°C
Minimum Temperature Alarm
Threshold. A temperature below
this threshold will set the alarm
(bit 0 of the Alarm Status
Register).
If the minimum temperature
threshold is to be change to
10°C then set as follows:
>)D0=+10.0
