SYSTEM INFORMATION

With the power switch on, swipe the touchscreen from left to

right on any screen to show the System Information screen.

Figure 25. System Information Screen

Here you will find product information such as model number,

serial number, firmware version, calibration date, along with

contact information for support.

Cancel will return the unit to

the previous screen.

Restore factory default settings will

restore all settings to the factory default, erasing IntelliTune

data, laser and temperature setpoints, transfer functions, etc.

Any customer-defined sensors will remain stored, however.

TC OPERATING INSTRUCTIONS

The LDTC LAB does not support TEC/RH that are

connected to the laser case.

ACCESS THE TC SCREENS

Ensure that the instrument is on the TC Screens

by pressing the TC Screen button if the TC

Screen is not active.

SET TC LIMITS

1. Press to access the TC Limit Screen.

2. Press

+ Limit Current, - Limit Current, Max

Temp, and/or Min Temp values and rotate the

adjustment knob to change each value. The text

will revert to blue when set.

Figure 26. TC Limit Screen

NOTES:

• The

Limit Currents should not exceed the damage current

threshold of the thermoelectric. To operate a resistive heater,

set one limit to

OFF.

• If the

Max Temp or Min Temp limits are exceeded, current output

to the thermoelectric will be disabled. This status is reported

remotely so the user can take action. Remote commands

can be used to trigger the laser diode current to be disabled

simultaneously (LASer:ENABle:OUTOFF).

• If the controller is running at limit current, the TC control icon and

limit icon will be ringed with red.

SELECT A SENSOR

The sensor choice determines the sensor voltage to

temperature relationship and which sensor pins are monitored

on the 15+2 D-SUB.

1. Press to access the Sensor Screen.

2. Press the blue sensor name and turn the

adjustment knob to cycle through the factory

default sensor types or any user-defined

sensors that were setup remotely.

The factory default sensors cannot be edited or deleted. They

are:

• Thermistor 5 kΩ 10 µA

• Thermistor 5 kΩ 100 µA

• Thermistor 10 kΩ 10 µA

• Thermistor 10 kΩ 100 µA

• Thermistor 20 kΩ 10 µA

• Thermistor 20 kΩ 100 µA

• Thermistor 50 kΩ 10 µA

• Thermistor 50 kΩ 100 µA

• Thermistor 100 kΩ 10 µA

• Thermistor 100 kΩ 100 µA

• RTD 2-wire, 100 Ω DIN

• RTD 2-wire, 1 kΩ DIN

• Linear IC Voltage Sensor

• Linear IC Current Sensor
