INTYPE
Input Type Parameter Command
Input:
INTYPE <input>, <sensor type>, <compensation>[term]
Format:
a,n,n
<input>
Specifies input to configure: A or B.
<sensor type>
Specifies input sensor type. Valid entries:
0 = Silicon Diode
5 = NTC RTD
1 = GaAlAs Diode
6 = Thermocouple 25 mV
2 = 100
Ω
Platinum/250
7 = Thermocouple 50 mV
3 = 100
Ω
Platinum/500
8 = 2.5 V, 1 mA
4 = 1000
Ω
Platinum
9 = 7.5 V, 1 mA
<compensation> Specifies input compensation where 0 = off and 1 = on. Reversal for thermal
EMF compensation if input is resistive, room compensation if input is
thermocouple. Always 0 if input is a diode.
Example: INTYPE
A,0,0[term]
– Sets Input A sensor type to silicon diode.
INTYPE?
Input Type Parameter Query
Input:
INTYPE? <input>[term]
Format:
a
<input>
Specifies input to query: A or B.
Returned:
<sensor type>, <compensation>[term]
Format:
n,n
(Refer to command for description)
KEYST?
Keypad Status Query
Input: KEYST?
[term]
Returned:
<keypad status>[term]
Format:
n
1 = key pressed, 0 = no key pressed.
Remarks:
Returns keypad status since the last KEYST?. KEYST? returns 1 after initial power-up.
KRDG?
Kelvin Reading Query
Input:
KRDG? <input>[term]
Format:
a
<input>

Format:
±nnnnnn
Remarks:
Also see the RDGST? command.
LDAT?
Linear Equation Data Query
Input:
LDAT? <input>[term]
Format:
a
<input>
Specifies which input to query: A or B.
Returned:
<linear value>[term]
Format:
±nnnnnn
Remarks:
Also see the RDGST? command.
