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

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

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

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

Max Iteration

for W atts

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

Calibration

WRATE

CD

1

+20732

Entry for W RATE 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

Calibration

Watts

CF

mW

120.000

Target W atts used for calibration.

If the target W atts for

calibration is 240, enter the

following:

>)CF=+240.000

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
