Both primary and secondary displays are 5-digit on the liquid crystal display (LCD) with a maximum
resolution of 50,000 counts and automatic polarity indication. Backlight available.
– 9.6 V Ni-MH rechargeable batteries: 1.2 V x 8 pieces. No cadmium, lead or mercury.
– External switching adapter: AC 100 V to 240 V, 50/60 Hz input and DC 24 V/2.5 A output.
– Battery charging: 9.3 VA typical
– Sourcing of constant current at 25 mA, maximum load: 5.5 VA typical on 24 V DC adapter, 2.4 VA
typical on 9.6 V batteries
– Meter only: 1.8 VA typical on 24 V DC adapter, 0.6 VA typical on 9.6 V batteries
Assuming fully-charged Ni-MH batteries:
Meter only: 20 hours (approximately)
Source/Meter: 4 hours (approximately)
will appear when voltage drops below 9 V (approximately)
Three hours (approximately) in 10 °C to 30 °C environment
NOTE: Prolonged charging is required if battery is fully discharged
Three readings/second, except for:
– AC+DC: 1 reading/second
– Frequency and duty cycle (> 1 Hz): 1 reading/second
– Pulse width (> 1 Hz): 0.25 to 1 reading/second
> 90 dB at DC, 50/60 Hz ± 0.1% (1 kΩ unbalanced)
> 60 dB at DC, 50/60 Hz ± 0.1%
