To zoom in, touch anywhere within the right half of the plot. To zoom out, touch the left half of
the plot (but not left of the Y axis). You can also drag the plot left or right to see older or newer
data; t

no longer automatic to return to
viewing real-time data.
Test the o utputs
is working by setting its current or power to a low value and seeing if any current flows. To do
this, connect your heater to the
back panel and set the output as follows:
1. Enable the outputs by pressing the Output Enable key twice. The red Output Enable light
should turn on.
2. Highlight the appropriate output channel on the Select screen, then press the Channel key to
display the channel setup screen.
3. If you selected one of the ±10V analog I/O channels to drive your heater, make the channel

damage your system).

CTC100 is not detecting the heater.
6. Use a temperature sensor to verify that your heater is warming up.
7. To turn the current off, touch the Off button on the channel setup screen.
Verify that the heater leads are not shorted to ground or to each other.
Measure the heater resistance with a multimeter
between 10 and
about 1k . Higher resistances are acceptable but the heater may not get very hot. Lower
resistances may cause the CTC100 to overheat.
Monitors
resistance
the same as what you measured with a multimeter? Is the voltage pegged at 55V or the
current at 2A?
Verify that the PID mode is set to off.
that the output value that you entered.
Set the data logging rate
By default, the CTC100 logs three data points per second for each channel. To change this rate
for all channels, press the Setup key on the front panel and then t Under
th
interval only affects how often data is recorded; it does not affect ADC sampling or PID feedback
performance.
Each channel can be assigned its own data logging rate; see the description of the
Channel.Logging control on page 67.
