9 ..... WIRE touch-screen key to select the material of measured wire (Cu or Al), coating (PVC, BUTYL

RUBBER or EPR/XLPE), section (1, 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50 or 70 mm

) and number of

conductors (1

 99). Currently selected material is displayed on the bottom of the key.

10 ... Measurement result (in green colour - result OK, in red colour - result not OK).
11 ... Real time clock (hh.mm.ss).
12 ... Unit of the test result (

).

13 ... Measurement result status (symbol

in green colour - result OK, symbol

in red colour - result

not OK).

5.6.2. LIMIT VALUE EXPLANATION

There are five possibilities to select the limit prospective short-circuit current I

SC LIM

, which is the bases

for final evaluation.

STD - no verification.

No limit is used in this case meaning test result is not evaluated and is therefore always considered as
neutral (displayed in white colour)

kA - verification if short-circuit current is lover than breaking capacity of involved over-current protection
device.

Measured I

SC MAX

must be lower or equal than entered breaking capacity Ib of involved over-current

protection device, where breaking capacity Ib can be selected among the following values:
- Ib (breaking capacity)

1, 1.5, 3, 4.5, 6, 10, 15, 16, 20 or 25 kA

t - verification if over-current protection device reacts before wires are overheated and thus damaged.

On bases of measured I

SC MAX

and entered over-current protection device (PROTECTION) and

nominal current of the over-current protection device (In) trip out time of the over-current protection

device (t) is calculated. See the evaluation equation in the table “PROSPECTIVE SHORT-CIRCUIT
CURRENT CALCULATION” below. Entered parameters can be selected among the following values:
- PROT (type of protection)

MCB B, MCB C, MCB D, MCB K, FUSE gG or FUSE aM

- In (nominal current)

- 6, 10, 13, 16, 20, 25, 32, 40, 50 or 63 A (MCB B)

- 0.5, 1, 1.6, 2, 4, 6, 10, 13, 16, 20, 25, 32, 40, 50 or 63 A (MCB C)

- 0.5, 1, 1.6, 2, 4, 6, 10, 13, 16, 20, 25 or 32 A (MCB D, MCB K)

2, 4, 6, 8, 10, 12, 16, 20, 25, 32, 40, 50, 63, 80, 100, 125, 160,

200, 250, 315, 400, 500, 630, 800, 1000 or 1250 A (FUSE gG)

- 2, 4, 6, 8, 10, 12, 16, 20, 25, 32, 40, 50, 63, 80, 100, 125, 160,

200, 250, 315, 400, 500 or 630 A (FUSE aM)

- MATERIAL (wire material)

Cu (Cupper) or Al (Aluminium)

- COATING (wire coating)

PVC, BUTYL RUBBER or EPR/XLPE

- SECTION (wire section)

1, 1.5, 2.5, 4, 6, 10, 16, 25, 35, 50, 70 mm

- N (number of conductors)

 99

TRIP CURRENT - verification if over-current protection device reacts within set time at measured short-

circuit current.
On bases of measured I

SC MIN

and entered over-current protection device (PROTECTION) and nominal

current of the over-current protection device (In) trip out time is calculated which must be lower than or
equal to entered Tset. Entered parameters can be selected among the following values:
- PROT (type of protection)
