178 LEYBOLD DIDACTIC · GENERAL CATALOGUE CHEMISTRY
Digital multimeter
The demonstration multimeter from LEYBOLD DIDACTIC for all natural
science subjects: versatile, accurate and sturdy. This microprocessor-
controlled instrument is characterized by high accuracy, enhanced resolution
and extreme ease of use. The menu-driven user set-up is actively supported
by the display and LEDs. The measuring range is displayed alphanumerically.
A plug-in power supply and two measuring leads with safety plug and test
probe are included in the scope of delivery. Using the separately available
data output module (> 667 909), these meter can be connected directly to
a printer, computer or chart recorder. This unit is also supplied with a software
program which enables computer-supported measured value recording
and evaluation in conjunction with the data output module (> 667 909)
Display: LED, 4 1 / 2 digit, 26 mm high,
(7-segment, numeric) for measured value, LED 2-digit, 14 mm high
(alphanumeric) for unit of measure, automatic negative indicator
Measuring ranges:
200 mV ... 1000 V DC / (10 µV ... 0.1 V)
200 mV ... 600 V AC / (10 µV ... 0.1 V)
200 µA ... 20 A AC/DC / (10 nA ... 1 mA)
200 Ohm ... 20 MΩ (10 mΩ ... 1 kΩ)
Overload protection:
1200 V DC / 700 V AC 2.5 A fuse
300 V DC / 270 V AC (Ω-range)
Inputs: V - Ω/2 A/20 A
Internal resistance 1MΩ (in voltage measuring range)
Measuring range selection: automatic, semiautomatic or manual
Voltage supply 13 V AC/1.3 A via plug-in power supply
(included in scope of delivery)
Dimensions:
200 x 140 x 150 mm (> 667 908)
200 x 297 x 160 mm (> 667 453)
Weight: 1.1 kg (> 667 908) / 1.5 kg (> 667 453)
Data outputs retrofittable via plug-in unit (data output module, > 667 909):
serial interface (RS 232), parallel interface (Centronics),
analog (recorder) output
All outputs are electrically isolated from the inputs.
