MODEL 1000N
Continuity Testing:
0.1Ω to 100Ω (typical accuracy: ± 5% of reading, max: ± 10% of reading or 5 mΩ)
The logarithmic scale is the same for the Ω and KΩ range. The 0.1Ω is calibrated at the output
terminal of the instrument. You need to subtract the resistance value of the leads from your
measurement if you need the accuracy under 10Ωs.
DC or AC Voltage Measurements:
In order to ensure that the system under test is not energized, the instrument functions as a
voltmeter as soon as it is connected, provided the push-to-measure button has not yet been
pressed. This is the case for every range selected.
Time Constant:
Charging time
Discharging time
Safety Features:
• This instrument is capable of withstanding overloads of up to 600 V for any selected function.
• The continuity range is protected by a fuse inserted in the "G" (Guard) terminal and is
accessible when the battery compartment is removed.
Influence:
• Temperature: Twice the accuracy per 10° C variation
Supply voltage: Half the accuracy for battery voltages between 9 and 13 Volts
• Humidity: No significant influence up to 40° C and up to 70% relative humidity
Dielectric Strength:
• 4000V RMS at 50 Hz for 1 minute between all input terminals and any accessible metal
portions of the instrument.
• Model with AC power supply accessory: Add test at 4000V RMS at 60 Hz for 1 minute
between the AC outlet and any accessible metal portions of the instrument.
