CALZ
Zero Offset Calibration Constant Command
Input:
CALZ <type>, <range>, <value>[term]
Format:
n,n,±nnnnnnn
<type>
Specifies the item to calibrate. Valid entries are:
1 = 100 mA hall current source (not used)
2 = 10 mA hall current source (not used)
3 = 1 mA hall current source (not used)
4 = Analog Outputs (1-3)
5 = Temperature
<range>
Specifies the range of the item to calibrate. Valid entries are:
1 = 300
μΩ
range
(hall current source, not used)
, 10

<value>
Zero offset calibration constant value.
Remarks:
The range variable is ignored but needs to be sent for types that do not need to specify a range (types 2,
3, and 4). A range value of 1 should be sent for those types. The hall current sources do not have a
calibrated zero. The offset is corrected using the Zero Probe function.
CALZ?
Zero Offset Calibration Constant Query
Input:
CALZ? <type>, <range>[term]
Format:
n,n
<input>
1 – 5
<type>
1 – 5
Returned:
<value>[term]
Format:
±nnnnnnn
(Refer to command for description)
CSMODE
Hall Current Source Mode Command
Input:
CSMODE <mode> [term]
Format:
n
<mode>
Specifies the hall current source mode. Valid entries are:
0 = Current off
1 = Normal mode (current reversal)
2 = Positive current
3 = Negative current
Remarks:
Configures the hall current source mode. The current output (100 mA, 10 mA, or 1mA) is dependent
on range (see HALLCS).
