2KΩ 1Ω
20KΩ 10Ω
200KΩ 100Ω
± (0.8% rdg + 1 digit)
2MΩ 1KΩ
20MΩ 10KΩ ±(1% rdg + 2 digits)
200MΩ 100KΩ ± [ 5% (rdg-10 + 10 digits) ]
VOLTAGE AT OPEN CIRCUIT: ≤700mV (200MΩ range, open circuit voltage
around 3V).
OVERLOAD PROTECTION: All ranges 250VDC or AC RMS.
CAUTION: At 200MΩ range, as test lead is short circuit the LCD display 10 digits
is normal, deduct the 10 digits from the measured reading during
measuring.
