Remote Operation
CRDG?
Query Celsius Reading for a single Input or All Inputs
Input: CRDG?
<input>
Returned: <Celsius value>
.
Format:
+/-nn.nnn[term]
.
Or if all inputs are queried:
<Input 1 Celsius Value>,<Input 2 Celsius Value>,<Input 3 Celsius Value>,<Input 4
Celsius Value>,<Input 5 Celsius Value>,<Input 6 Celsius Value>,<Input 7 Celsius
Value>,<Input 8 Celsius Value>
. Format:
+/-nn.nnn,+/-nn.nnn,+/-nn.nnn,+/-nn.nnn,+/-
nn.nnn,+/-nn.nnn,+/-nn.nnn,+/-nn.nnn
Remarks:
Returns the Celsius reading for a single input or all inputs. <input> specifies which input(s) to
query.
0
= all inputs,
1-8
= individual input.
NOTE:
Use
0
(all inputs) when reading two or
more inputs at the maximum update of 16 rdgs/sec.
CRVDEL
Delete User Curve
Input: CRVDEL
<curve>
Returned:
Nothing.
Remarks:
Deletes a user curve.
<curve>
specifies which curve to delete (
21-28
) for inputs 1-8.
Example: CRVDEL 21[term] -
Deletes User Curve
21
. (input
1
user curve).
CRVHDR
Configure
Curve
Header
Input:
CRVHDR <curve>, <name>, <SN>, <format>, <limit value>, <coefficient>

21
-
28
) for inputs 1-8.
<name>
Specifies curve name. Limited to 15 characters.
<SN>
Specifies curve serial number. Limited to 10 characters.
<format>
Specifies curve data format.
2
= V/K,
3
= Ohm/K,
4
= log Ohm/K
<limit value>
Specifies curve temperature limit in Kelvin.
<coefficient>
Specifies curve temperature coefficient.
1
= negative,
2
= positive.
Example: CRVHDR
21,Custom,00011134,2,325.0,1[term] -
Configures User Curve 21, (input 1 user
curve), with a name of CUSTOM, serial number 00011134, data format of volts vs Kelvin,
upper temperature limit of 325 K, and negative coefficient.
CRVHDR?
Query Curve Header
Input: CRVHDR?
<curve>

Format:
aaaaaaaaaaaaaaa,aaaaaaaaaa,n,nnn.nnn,n[term]
Remarks:
Returns a standard or user curve header. See
CRVHDR
command for parameter
descriptions.
<curve>
specifies which curve to query.
1-5
= Standard Diode Curves,
6 -9
=
Standard Platinum Curves,
21-28
= User Curves.
NOTE:
Curve Locations
10-20
not used.
CRVPT
Configure Curve Data Point
Input:
CRVPT <curve>, <index>, <units value>, <temp value>
Returned:
Nothing.
Remarks:
Configures a user curve data point.
<curve>
Specifies which curve to configure (
21
-
28
) for inputs 1-8.
<index>
Specifies the points index in the curve (
1
-
200
).
<units value>
Specifies sensor units for this point to 6 digits.
<temp value>
Specifies corresponding temperature in Kelvin for this point to 6 digits.
Example: CRVPT 21, 2, 0.10191, 470.000[term] -
Sets User Curve 21 (input
1
user curve) second data
point to 0.10191 sensor units and 470.000 K.
