1000 V d.c. when this requirement is specified, also aircraft
and tele-communications equipment can be tested at the
relatively low 100 V d.c. and 110 V to 120 V a.c. systems can
be tested using 250 V d.c.
Test leads with fused prods are available and it is
recommended that these be used when checking that
equipment has been isolated from the supply (by
performing a voltage test), especially in high energy
situations.
SPECIFICATION
Insulation Range
Insulation Resistance: 0.1 Ω - 2000 MΩ (0.1 Ω -1000 MΩ for
MJ160)
Accuracy: ±1.25% of fsd on a 2.8 in. (71.1mm) arc length
Nominal Test Voltages
d.c: 100 V , 250 V , 500 V , 1000 V .
(MJ160 is 50 V , 100 V , 250 V , 500 V)
Accuracy
250 V , 500 V , 1000 V +30%, -0% max.
50 V , 100 V , +40%, -0% max.
Midscale: 4 MΩ (2 MΩ for MJ160)
Short Circuit Current: 1.9 mA
(0.65 mA for MJ160)
Maximum Load Capacitance: 1µF with less than ±0.1" pointer
movement
Discharge: Up to 1 µF capacitance is discharged from 1000 V to
less than 42.4 V in less than 4 secs
Resistance Range
0.1 Ω - 5000 Ω
Test Voltage characteristics
Open circuit Test voltage: 3 V ±0.2 V
Short Circuit Current: 2 mA ±10%
Accuracy: ±1.25% of fsd on a 2.8 in. (71.1mm) arc length:
Safety Voltage Check
Voltage measurement: 0.1 V - 600 V a.c; the meter is RMS
calibrated and average responding
Safety voltage indicator: Indicates the presence of d.c. voltages.
Scaling is not the same as the a.c. meter. True d.c. voltage equals
scale reading divided by 2.22
Accuracy: 2.5% of full scale
Power Supplies
MJ159 and MJ160: Low voltage brushless a.c. generator. Cranking
speed between 130 rpm and 170 rpm
MJ359: Dual operation low voltage brushless a.c. generator or 120
V 50/60 Hz mains (line) supply
MJ459: Six IEC LR6 cells (AA) Battery life: not less than 1300
insulation or Resistance range tests
MJ559: Dual operation 120 V 50/60 Hz mains (line) supply and
rechargeable battery. Six Ni Cad cells (e.g. AA, NEDA 15 NC)
Safety
The instruments meet the requirements for double insulation to
IEC 1010-1(1995), EN 61010 (1995) to installation Category II, 300 V
phase to earth (ground), 600 V installation Category I
