CSET
Temperature Control Setup Parameter Command
Input:
CSET <channel>,<filter>,<units>,<delay>, <current/power>, <htr limit>,
<htr resistance>[term]
Format:
nn,n,n,nnn,n,n,
±
nnn.nnn
<channel>
Specifies which channel to control from: 1–16.
<filter>
Specifies controlling on unfiltered or filtered readings: 0 = unfiltered, 1 = filtered.
<units>
Specifies setpoint units: 1 = Kelvin, 2 = Ohms.
<delay>
Delay in seconds for setpoint change during Autoscanning: 1–255
<current/power>
Specifies heater output display in current or power: 1 = current, 2 = power.
<htr limit>
Maximum heater range: 1–8. (Refer to
HTRRNG
for detailed range listing.)
<htr resistance>
Heater load in ohms: 1–100,000.
Example:
CSET 16,0,1,30,1,8,100[term]
– The Model 370 controls from channel 16 unfiltered readings. The
setpoint is in Kelvin with a 30 second setpoint change pause time. The heater output is displayed in
current. The heater maximum range limit is set to 100 mA and the heater load is set to 100
Ω
.
