Seaward 200 PrimeTest - Manual (Page 15)

7.0 Electrical Specification
Appendix 1 specifies the operating error for all tests and functions of the
PrimeTest 200.
7.1 Earth continuity measuring range (rotary switch position , and IEC)
Measuring Range Resolution Accuracy Overload Protection
19.99 Ω 0.01 Ω ±5% +2 digits 300 V AC/DC
Analogue bargraph display 0 to 20 Ω
Bargraph accuracy 10%
Open circuit voltage >4VDC
Test current >200mA (0-2 Ω )
Input protection 0.5A (600V) quick blow fuse
An input voltage of ≥ 30 V AC/DC, detected between the + and - input measuring
terminals, disables the earth continuity measuring circuit. A repetitive audible
alarm is activated and a flashing high voltage symbol is displayed on the LCD.
The maximum number of continuity tests, with a duty cycle specified by
BS EN 61557-4 Section 6.6, is 1900 repetitions.
7.2 Insulation resistance measuring range (rotary switch position , , IEC
and M
Ω .
Measuring Range Resolution Accuracy Overload Protection
2M Ω 0.01M Ω ±2% +2 digits 300 V AC/DC
20M Ω 0.1M Ω ±2% +2 digits 300 V AC/DC
200M Ω 1M Ω ±5% +2 digits 300 V AC/DC
Analogue bargraph display 0 to 200M Ω and infinity
Bargraph accuracy 10%
Test voltage >500VDC at 1mA, <750VDC for o/c
Test voltage accuracy +20%, -0%
Test current <2mA for s/c
Input protection 0.5A (600 V) quick blow fuse.
An input voltage of ≥ 30 V AC/DC, detected between the + and - input measuring
terminals, disables the insulation resistance measuring circuit. A repetitive
audible alarm is activated and a flashing high voltage symbol is displayed on
the LCD.
The maximum number of insulation tests, with a duty cycle specified by
BS EN 61557-2 Section 6.7, is 2000 repetitions.
7.3 Resistance measuring range
Measuring Range Resolution Accuracy Overload Protection
19.99 Ω 0.01 Ω ±5% +2 digits 300 V AC/DC
1999 Ω 1 Ω ±5% +2 digits 300 V AC/DC
20.00K Ω 10 Ω ±5% +2 digits 300 V AC/DC
Analogue bargraph display 0 to 20K Ω and infinity
Bargraph accuracy 10%
Test current >200mA (0-2R)
Open circuit voltage > 4 V DC
Input protection 0.5A (600 V) quick blow fuse.
Zero compensation of the test leads up to 10 Ω . The internal buzzer sounds
when the measured resistance <10 Ω .
An input voltage of ≥ 30 V AC/DC, detected between the + and - input measuring
terminals, disables the resistance measuring circuit. A repetitive audible alarm is
activated and a flashing high voltage symbol is displayed on the LCD.
