• Sampling rate: 1 S/s
• This is accuracy by 6 and 1/2 digits resolution for 4 terminal resistance measurement or 2
terminal resistance measurement after zero compensation by NULL calculation. In the case
NULL calculation is not performed, 0.2Ω additional error is added to 2 terminal resistance
measurement.
• Maximum allowable voltage
Between Ω-COM terminals: 800 Vpeak (continuous), or 1100 Vpeak (for 1 minute)
Between Sense Hi-Lo: 200 Vpeak
• Terminal open voltage <17 V
