(7) The design of this device and its various approved embodiments are defined in the attachment to
this type approval test certificate.
(8) As the nominated body no. 0820 in accordance with article 9 of the EC council directive dated
March 23, 1994 (94/9/EC), the Testing and Certification Body ZELM Ex certifies conformance with
the basic health and safety requirements for the design and construction of devices and protection
systems for proper designated use in areas with an increased risk of explosion in accordance with
Appendix II of the directive.
The results of the test are documented in the confidential test report no. ZELM Ex 0510217162.
(9) The basic health and safety requirements are met by virtue of conformance with
EN 50 014: 1997+A1+A2 EN 50 020: 1994
(10) If the certification number is followed by an “X”, then this indicates that special conditions exist for
the safe operation of the device. These special conditions are contained in the attachment to this
certificate.
(11) This EC type approval test certificate only refers to the construction/design, checking and testing of
the specified device or protection system in accordance with directive 94/9/EC. Further require-
ments contained in this directive may apply with regard to the manufacturing process and the supply
of the device or protection system. Such requirements are not covered by this certification.
(12) The device must be labelled with the following information:

EC type approval test certificate ZELM 02ATEX 0120 X
(15) Description of the device
The explosion-protected mA calibrator 707Ex serves as a compact source and measuring instru-
ment for mobile measurements of current loops (0...24 mA) and DC voltages (up to 28 V) in areas
with an increased risk of explosion as well as in areas with no increased risk of explosion.
The device is equipped with a power supply in the form of a battery of type 6LR61. This battery
must only be changed outside the area with increased risk of explosion.
Within the ex-area the device must be carried in the designated holster.
Electrical data
Power supply circuit from an integral battery, EEx ia IIC
The internal circuits are intrinsically safe.
Measuring circuit type of ignition protection: intrinsically safe, EEx ia IIC
for connection to certified intrinsically safe circuits
Maximum values:
a) Current measuring circuit, Uo = 27.6 V DC
active (0...24 mA) (linear characteristic) Io = 96.9 mA
Max. perm. external capacitance Co = 76 nF
Max. perm. external inductance Lo = 2.5 mH
b) Voltage measurement (0...28 V)Ui=30V DC
Ii = 24 mA
Effective internal capacitance Ci = 10 nF
The effective internal inductance is negligibly small.
Permitted ambient temperature -10 °C to +50 °C
Measurements on non-intrinsically safe circuits
Measurement inputs Maximum values: U = 30 V DC
I=24mA
Note:
The operating instructions must be followed.
The battery must be changed outside the ex-area.
Within the ex-area the device must be carried in the designated holster.

(17) Special conditions
The battery must be changed outside the ex-area. Only the battery type(s) listed in the operating
instructions must be used.
Within the ex-area the device must be carried in the designated holster.
(18) Basic health and safety requirements
satisfied by virtue of the standards
