• Excellent visibility in bright sunlight
• Selectable input resistance
• Large liquid crystal digital display

General Information

• Right Meter: Selectable Input Resistances of 10, 25, 50,100 & 200 megohms on all ranges from 200 mV to 200 V; 20 mV range fixed at 1000 ohms.
• Left Meter: 10 Megohms Input Resistance on all ranges from 200 mV to 20 V; 20 mV range fixed at 1000 ohms.
• RFI Rejection: A major design achievement was to eliminate the effects of RFI, and offer accurate, repeatable readings.
• Logic: C-MOS LSI; crystal controlled timing.
• AC Rejection: Normal mode 50/60/400 Hz greater than 60 dB.
• Zero: Automatic.
• Polarity: Automatic (negative symbol displayed, positive assumed).
• Decimal Point: Automatic.
• Battery Life: Amplifiers approximately 150 hours continuous. Low battery voltage indication incorporated into display. Other batteries have life dependent upon use.
• Battery Types: Only standard batteries used: D-size, penlight & 9 V transistor types.
• Accuracy: DC 1% of reading + 1 digit; AC 2% reading + 1 digit.
