PROBLEM

POTENTIAL CAUSES

SOLUTIONS

The Enable button does not turn on

The button has been turned on and off within

2 seconds.

The button cannot be pressed faster than every

2 seconds.

The instrument experienced an internal fault.

(See

Error Messages.)

The instrument will remain disabled until

manually powered off and then on using the rear

panel power switch.

The instrument heatsink temperature has

exceeded 70ºC.

Allow the instrument to cool down and then press

the front panel power button.

The front panel Power button is not on.

Press the Power button on the front panel to

enable the display.

The instrument is on but the front

panel display is blank

The instrument experienced an internal fault.

(See

Error Messages.)

Switch the back panel power button off and then

on again, and turn the front panel power button on.

The internal temperature has reached an

unsafe level.

Allow the instrument to cool down and then switch

the back panel power button off and then on again,

and turn the front panel power button on.

The front panel Power button is pulsing on

and off in standby mode.

Press the Power button on the front panel to enable

the display.

The date and time on my TC scan file

are wrong

The TC LAB instrument does not have a realtime

clock. When a TC scan file is created, the date and

time stamp are randomly chosen.

The TC scan files are not in the order

that they were created

Some files may have been deleted off of the

USB flash drive.

When files are deleted off of the USB flash drive

and new files are saved to it, the new files are

given sequentially the names of the deleted files.

Unable to create new TC scans

There are too many files on the USB flash

drive.

Delete files from the USB flash drive.

I can’t find my TC scan files

TC scan files are named sequentially

If files have been deleted from the flash drive, any

new files added are named sequentially and have

the names of the deleted files.

The output switched off unexpectedly

The instrument detected an internal error.

(See

Error Messages.)

Switch the back panel power button off and then

on again, and turn the front panel power button on.

The internal temperature has exceeded

70ºC.

Allow the instrument to cool down and then press

the front panel power button.

My instrument doesn’t show up in the

list.

(Remote Only)

Your instrument may not be turned on.

Power up the instrument and click

Refresh on the

Choose Instrument window.

Your instrument may not be plugged in to the

computer.

Check that either a USB or Ethernet cable is tightly

connected to the instrument and to the computer.

Your instrument may be on a different

sub-net.

Add the sub-net to the

Choose Instrument

window and then click

Refresh.

IntelliTune fails because of a sensor

error

Sensor voltage may be too high or too low,

which triggers a bias current change.

Choose a setpoint such that the sensor voltage

will be between 0.25 V and 12.075 V. The sensor

signal will be in range during all of the sweeps and

not trigger a bias current change.

Use the remote command TEC:BIAS to set a

fixed sensor bias current. Review the TCS Series

Thermistors Datasheet for temperature-resistance-

voltage relationships.

IntelliTune

stopped

without

error message or updating the PID

coefficients.

If a new sensor was chosen, it is possible

that the Resistive Hi and Lo limits no longer

apply.

Go to the

Settings screen and change to

Resistance Mode. On the Limit screen, update

the

RHI and RLO numbers to bracket the setpoint.

Change back to

Temperature Mode and retry

IntelliTune scan.
