Safety Guidelines

General Guideline
CAUTION

Do not place any heavy object on the instrument.
Avoid severe impact or rough handling that leads to damaging the instrument.
Do not discharge static electricity to the instrument.
Use only crimped wires, not bare wires, for the terminals.
Do not block the cooling fan opening.
Do not disassemble the instrument unless you are qualified.
The equipment is not for measurements performed for CAT II, III and IV. (Measurement categories) EN 61010-1:2010 specifies the measurement categories and their requirements as follows. The instrument falls under category II.
Measurement category IV is for measurement performed at the source of low-voltage installation.
Measurement category III is for measurement performed in the building installation.
Measurement category II is for measurement performed on the circuits directly connected tothe low voltage installation.
0 is for measurements performed on circuits not directly connected to Mains.

Power Supply

AC Input voltage range: 100-120VAC/200-240VAC (90-132VAC/180-250VAC)
Frequency: 47-63Hz
Power: 90VA Max
To avoid electrical shock connect the protective grounding conductor of the AC power cord to an earth ground.

Cleaning

Disconnect the power cord before cleaning.
Use a soft cloth dampened in a solution of mild detergent and water. Do not spray any liquid.
Do not use chemicals containing harsh material such as benzene, toluene, xylene, and acetone.

Operation Environment

Location: Indoor, no direct sunlight, dust free, almost non-conductive pollution (Note below)
Temperature: 0°C to 40°C
Humidity: 0 to 85% RH
Altitude: <2000m (Pollution Degree) EN 61010-1:2010 specifies the pollution degrees and their requirements as follows. The instrument falls under degree 2.
Pollution refers to “addition of foreign matter, solid, liquid, or gaseous (ionized gases), that may produce a reduction of dielectric strength or surface resistivity”.
Pollution degree 1 : No pollution or only dry, non-conductive pollution occurs. The pollution has no influence.
Pollution degree 2 : Normally only nonconductive pollution occurs. Occasionally, however, a temporary conductivity caused by condensation must be expected.
Pollution degree 3 : Conductive pollution occurs, or dry, non-conductive pollution occurs which becomes conductive due to condensation which is expected. In such conditions, equipment is normally protected against exposure to direct sunlight, precipitation, and full wind pressure, but neither temperature nor humidity is controlled.

Storage environment

Location: Indoor
Temperature: -20°C to 70°C
Humidity: <90% RH

Disposal
Do not dispose this instrument as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased. Please make sure discarded electrical waste is properly recycled to reduce environmental impact.

Power cord for the United Kingdom
When using the instrument in the United Kingdom, make sure the power cord meets the following safety instructions.
NOTE: This lead/appliance must only be wired by competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in accordance with the following code:

As the colours of the wires in main leads may not correspond with the coloured marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with either the letter E, the earth symbol or coloured Green/Green & Yellow.
The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, a cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.
Any exposed wiring from a cable, plug or connection that is engaged in a live socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be immediately destroyed and replaced in accordance to the above standard.

If the unit doesn’t turn on, press the On/Standby key.
The ON/STBY key will go from standby (red) to on (green).
The unit will show the splash screen and then load the settings from when the unit was last powered down.
Note
If the T3EL fails to start up properly or does not turn on, please see you local distributor.

Conventions
The following conventions are used throughout the user manual. Read the conventions below for a basic grasp of how to operate the T3EL Series menu system using the front panel keys.

Soft Menu keys
The F1 to F5 function keys at the bottom of the display correspond directly to the soft-menu keys on top.

Select Sub Menu
Pressing this type of soft-menu key will enter a submenu.

Toggle Parameter or State

This type of soft-menu icon has the function/item on the top of the label and the selected setting or mode on the bottom of the label.
Repeatedly press the associated function key (F1-F5) to cycle through each setting. For example, repeatedly pressing the Mode softmenu key will cycle through the CC, CR, CV and CP modes.
For some parameters, a popup window will also appear. Selection of the setting is the same. Repeatedly pressing the relevant function key (F1-F5) will cycle through each setting. The selection on the popup window will also be reflected on the label.

Parameter Input
The scroll wheel, Enter key and number pad can be used to edit parameter values.

Use the scroll wheel to move the cursor to the desired parameter.
A scroll bar is shown when there are additional parameters off-screen.
Press the Enter key to select the parameter. The parameter will become highlighted in white.
Then use the number pad* or scroll wheel** to edit the parameter value.
Press the Enter key again to finish editing the parameter value.

Clearing a Value
When editing a parameter with the number pad, pressing the Clear key will restore the parameter to the previous value.

Using the Scroll Wheel to Edit a Parameter**

To edit a parameter using the scroll wheel, simply turn the scroll wheel. Clockwise increases the value, counterclockwise decrease the value.
Pressing the scroll wheel when a parameter is highlighted allows you to change the step resolution. There are two different step resolution methods: Step Mode and Cursor Mode.
Step Mode: This is the default step resolution method and will only be available to use when it is applicable (Indicated by Fine or Coarse in the Operation Status panel).
When a parameter is highlighted (step 3 above) pressing the scroll wheel will toggle the step resolution between fine and coarse.
Cursor Mode: This method must first be enabled before it can be used. Pressing the scroll wheel when a parameter is highlighted allows you to set the step resolution by a digit value. An orange line will appear under the currently selected digit value. Repeatedly pressing the scroll wheel moves to the next digit.

Entering Alphanumeric Characters
When renaming files, creating memos or notes, you will be required to enter alphanumeric characters when the character entry screen appears.
Only alphanumeric characters as well as space [ ], underscore [_] and minus [-] characters allowed.

Use the scroll wheel to move the cursor to the desired character.
Press the Enter key or Enter Character[F1] to select a character.
To delete a character, press Back Space[F2].
To save the file name or memo, press Save[F3].
