LIMITED GUARANTEE and LIABILITY
SIKA guarantees that this product is free of any manufacturing defects under normal conditions of use
and care. The guarantee period is one year with effect from the date of despatch. Parts, product re-
pairs and services are guaranteed for a period of 90 days. This guarantee only applies to the original
purchaser or to the end user if the latter is a distributor authorised by SIKA, and it does not apply to
fuses, inter-changeable batteries or any product which, according to SIKA, has been tampered with,
modified, neglected or damaged by accident or subjected to abnormal conditions of use and handling.
SIKA guarantees that the software will operate for the most part in compliance with the functional
specifications for a period of 90 days and that said software was recorded on non-faulty media. SIKA
does not guarantee that the software does not contain any mistakes or that it operates continuously.
The distributors authorised by SIKA shall apply this guarantee to products sold new and which have
not been used, but they are not authorised to apply an extended or different guarantee on behalf of
SIKA. Guarantee support is offered if the product has been purchased through a sales outlet author-
ised by SIKA or if the purchaser has paid the applicable international price. SIKA reserves the right to
invoice the purchaser the import charges for repaired parts or spare parts if the product purchased in
a country is sent to another country for repair.
The guarantee obligation on the part of SIKA is limited, at the discretion of SIKA, to refunding the pur-

61010) as well as on the electromagnetic compatibility of the electrical measuring instruments (EMC:
EN61326).
These instructions for use contain information and warnings which must be observed by the user to
protect the latter against the dangers of electricity, to ensure the safe operation of the device and to
protect it against any mishandling which could damage or compromise the safety of use of the device.

(without AA batteries or rechargeable battery pack).
1.3.3 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. If
not, you can return the device to us, and we will take care of its disposal free of charge.
1.3.3.1 Waste generated by the device
List of waste classified according to the decree published in the Official French Gazette dated 20th
April 2002. Decree no. 2002-540.
•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 (or NI-MH batteries).
•15.01.02: Packaging
ABS plastic device casing.
Elastomer conduit.
1.3.4 Device destruction procedure
Opening the device: unscrew the screw on the battery compartment, followed by the 5 screws secur-
ing 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 chap-
ter).
In the case of the pack of batteries, there are 2 contaminants: NI-MH (Nickel-Metal Hybride) batteries
and a PCB. Separate these 2 items.
1.3.5 Instructions
The device was designed to operate safely if the instructions provided in the accompanying docu-
ments are followed. Any other use may jeopardise the safety of the operator. Any use other than
those specified in the instructions is therefore dangerous and forbidden.

UC RTD.2 General
Technical changes reserved - 9 -
1.3.6 Making measurements
The measuring leads and wires must be in good condition and must be replaced if their insulation ap-
pears faulty (insulating material cut, burned, etc...).
When the instrument is connected to the measuring circuits the terminals can be dangerous, therefore
do not place your hands near a terminal, whether used or not.
Never exceed the protection value limits indicated in the specifications.
When the order of size of the measured value is not known, ensure that the starting measurement
range is has high as possible, or select automatic range change mode.
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 dan-
gerous 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 (option).
1.3.7 Defects and abnormal stresses
Every time you believe the protection may have been compromised, switch off the device and prevent
it from being switched back on unexpectedly.
The protection may be impaired in the following cases, for example:
•The device is visibly worn.
•The device is no longer able to make precise measurements.
•The device was stored in unfavourable conditions.
•The device has undergone severe stresses during transport.
1.3.8 Definitions
1.3.8.1 Definition of the category and degree of pollution
CAT II 60V:
The notion of categories determines the maximum transient voltage that can be applied to the meas-
urement inputs (it is also called overvoltage category). For the SIKA UC RTD.2, the maximum per-
missible overvoltage is 60V (DC or AC)
POL 2:
The notion of pollution determines the clearance between circuits. Degree 2 authorises temporary
conductivity caused by condensation.

1.4 Maintenance
The device must always be repositioned in accordance with the instructions provided herein. Any in-
complete or incorrect assembly could compromise the safety of the operator.
The authority responsible must regularly ensure that all safety-related items are not worn and ensure
all the preventive maintenance operations required are performed.
Before opening the device for any maintenance operations, you must make sure that all the wires are
disconnected from the appliance.
All adjustments, maintenance and repair work on the open device must be avoided as much as pos-
sible and, when these are indispensable, they must be performed by qualified staff, who are well
aware of the risks involved.

2 Using the instrument
In order to use the device in all the safety required, all operators must read the paragraph on safety
carefully, along with the paragraph below.
2.1 Power-up
The device is delivered with 4 AA batteries of 1.5V each. It is wise to place these batteries in the
compartment provided for this purpose. To open up the compartment, unscrew the screw on the back
of the box. Once the batteries are in place, screw the cover back on.
Observe the polarity: an incorrect battery positioning could damage the device. The correct polarity is
indicated inside the compartment.
The figure below illustrates how to open the battery compartment as well as the correct positioning of
each battery.
2.1.1 Keyboard
The keyboard features:
•2 function keys (F1 and F2) for the selection of the various menus displayed on the screen.
•The navigator, consisting of 4 arrows (up (
↑
), down (
↑
),right (

), left (

)
•A clear key (CLEAR).
•A device on/off and backlighting on/off key (ON/OFF).
Press briefly to start the device. During operation, press briefly to turn the lighting on or off.
Press it longer for 2 seconds to stop the device.
•A validation key (VAL).
•A HOLD key allows you to suspend a process temporarily (when pressed briefly). If you press
it longer, this key makes it possible to switch from measuring mode to emission mode and
vice-versa.

2.1.3 USB connector
The UC RTD.2 is fitted with a USB connector (mini B) intended for uploading new software versions,
device adjustment and general connection to PC.
2.1.4 Screen
The UC RTD.2 is fitted with a graphic LCD display with back-lighting. The display resolution is 160 x
160 pixels. In normal operating conditions, the display is divided up into seven horizontal fields:
•The 1st field indicates the operating mode (Measurement, emission).
•The 2nd field indicates the date, time and battery charge.
•The 3rd field is reserved for icons indicating the operating mode
(related functions: Scaling, filtering…etc).
•The 4th field indicates the operating mode, the range and certain related functions.
•The 5th field indicates the value of the measurement or of the emission.
These values are expressed in Ω, °C, °F or %.
•The 6th field indicates (in measurement mode) the min., average and max. values of the
measurement.
•The 7th field indicates the function of keys F1 and F2.

2.1.5 Getting started (after power-up)
On power-up (inserting the batteries or accu pack), the device is automatically turned on (loading the
software in the memory). At this stage, we advise against connecting the device to an external circuit.
To avoid any signal conflicts, the device switches to measurement mode.
