Storage and transport temperature range limit: - 30°C to + 60°C (without the batteries).
A.4.3 Worn devices
Worn electrical devices can pollute the environment. We recommend you refrain from disposing of this device in an
ordinary waste bin, but rather that you use the recycling circuits available locally.
A.4.3.1 Waste generated by the device
List of waste classified:
16.02.14: Waste originating from electronic equipment:
Printed circuit boards making up the device
16.06.02: Batteries and storage battery (dangerous)
Alkaline batteries
3 V lithium battery (CR1225 type)
Or Ni-MH batteries (If the unit is equipped with an 12436-01 battery pack)
15.01.02: Packaging

A.4.3.2 Device destruction procedure
Open the device: unscrew the screw on the battery compartment, followed by the 5 screws securing the 2 shells.
Separate the 2 shells. Separate the PCB from the upper shell.
With regard to the batteries, you will find them in the battery compartment (see commissioning chapter).
In the case of the pack of batteries, there are 2 contaminants: NI-MH (Nickel-Metal Hybrid) batteries and a PCB. Separate
these 2 items.
A.4.4 Instructions
The unit is designed to be used in complete safety if the instructions given in the accompanying documents are followed.
Any use apart from those defined, may prejudice the safety of the operator and is therefore dangerous and forbidden.

Directives CE A
7
A.4.5 Making measurements
Measuring wires and leads must be in good condition and must be replaced if their insulation appears defective (insulation
cut, burned, etc.).
Never exceed the protection value limits indicated in the specifications.
Before changing function, disconnect the measuring wires from the external circuit. When voltage measurements are
being made, even weak ones, keep in mind that the circuits may feature a dangerous voltage for the operator compared to
the ground.
Do not make any measurements when the device is linked up to another device using the USB link or when the batteries
are being charged.
A.4.6 Unusual faults and stresses
Whenever it is believed that the protection has been damaged, switch off the unit and ensure that it is not used
prematurely.
The protection may have been damaged if, for example:
There is obvious damage to the unit.
The unit is no longer able to make accurate measurements.
The unit has been stored under unfavorable conditions.
The unit has been subjected to severe stress during transportation.
A.4.7 Definitions
A.4.7.1 Definition of the category and degree of pollution
CAT II 60V:
This notion of categories determines the maximum voltage which can be applied to the measuring inputs (it is also
referred to as the overvoltage category). For the TC621, the ceiling overvoltage is (DC or AC)
POL 2°:
The notion of pollution determines the clearance between circuits. Degree 2 authorizes temporary conductivity caused by
condensation.

A.5 Maintenance
The unit must always be set up according to the instructions in this notice. Any incomplete or poorly executed set up
may compromise the safety of the operator.
The responsible authority must ensure on a regular basis that factors affecting safety do not change with time and carry
out any necessary preventive work.
Before opening the unit for any maintenance operations, you must ensure that all wires are disconnected from the unit.
Any adjustment, maintenance or repair of an open unit must be avoided as far as possible and, if essential, must be
carried out by qualified personnel who are familiar with the risks involved.

B.1.7 Operating modes
There are 2 different operating modes:
Measurement mode (displayed in mV, Ohm, °C or °F)

Using the navigation key (), start the automatic increases phase (following the parameters programmed in the
CONFIGURATION/RAMP menu).
Using the navigation key (), you can decrease automatically starting from the max. programmed voltage (or
temperature).
Using the navigation key (), you can increase manually the voltage (or temperature) emitted (following the
parameters programmed in the CONFIGURATION/RAMP menu).
Using the navigation key (), you can decrease manually the voltage emitted starting from the max. programmed
voltage (or temperature).
The Hold key allows you to stop generating or to resume it
You can resume the generation of the ramp in step-by-step mode by pressing the navigation keys ( and  ) or in
automatic generation using the navigation keys ( and ).
Voltage or temperature generation / default editing?
The default emission mode is a mode that makes it possible to generate manually the values stored for the synthesizer
function.
Press the F2 key to display the edit menu.
Using the navigation keys ( and ), choose the Default values mode and confirm (VAL key).
Using the navigation keys ( and ), select the value that needs to be emitted.
Confirm using the VAL key.
Voltage / resistance or temperature generation / synthesizer?
Press the F2 key to display the edit menu.
Using the navigation keys ( and ), choose the Synthesizer mode and confirm (VAL key).
The values emitted are those programmed in the CONFIGURATION/Synthesizer menu (see the chapter entitled Related
functions).
Using the navigation key (), start the automatic increases phase (following the parameters programmed in the
CONFIGURATION/Synthesizer menu).
Using the navigation key (), you can decrease automatically starting from the max. programmed voltage (or
temperature).
Using the navigation key (), you can increase manually the voltage (or temperature) emitted (following the
parameters programmed in the CONFIGURATION/Synthesizer menu).
Using the navigation key (), you can decrease manually the voltage emitted starting from the max. programmed
voltage (or temperature).
The Hold key allows you to stop generating or to resume it
You can resume the generation of the ramp in step-by-step mode by pressing the navigation keys ( and  ) or in
automatic generation using the navigation keys ( and ).
The configuration of the parameters for the ramps and default values is explained in the chapter entitled “Related

D.1 Scaling
The scale correction function performs conversion operations between the electrical values measured and the physical
values converted.
This linearization operation makes it possible to correct partially the errors induced by non-linear sensor/converter
systems.
The Scaling function makes it possible to define up to 10 right-segments, i.e. 11 points, in order to approach as much as
possible the non-linear response curve, and to make the scale corrections according to each segment.
The pictogram  is displayed on the screen in the active window when the scaling function is enabled.
The Define/list of points menu makes it possible to program up to 10 lines of 2 values: X and Y= f(X).
In measurement mode: X = Value measured and Y = Value Displayed.
In emission mode: X = Value displayed and Y = Value emitted.
The lines entered are sorted according to the X in increasing order, to scale an X-value, the device seeks the 2 lines n and
m=n+1 which frame it, and extrapolates linearly: Y = Yn + (X-Xn) x (Ym-Yn)/(Xm-Xn)
Use the function keys to edit the points:
To add a line: enter X and Y, then enable the function key.
To select a line in a list, use the Up and Down navigation keys.
To delete a selected line, use the key.
To move from one field to the next, use the key.
The Define/parameters menu makes it possible to define the format (Number of digits displayed) and unit.
Once the parameters have been set, the scaling is automatically enabled. To disable it, enter the Configuration/Scaling
menu, select OFF and confirm by pressing the VAL key.
