Initial Start-Up – Setup 3 Initial Start-Up 3.1 Batteries Be certain to refer to chapter 10.2 regarding correct battery installation! Momentary battery voltage can be queried in the “Info” menu (see chapter 7.3). ! Attention! Disconnect the instrument from the measuring circuit before opening the battery compartment lid in order to replace the batteries. Display Illumination After the instrument has been switched on, background illumination can be activated by briefly pressing the ON / OFF | LIGHT key.
Initial Start-Up – Setup 3.4 Switching the Instrument Off Switching the Instrument Off Manually Ð Press the ON / OFF | LIGHT key until 0FF appears at the display. ON / OFF LIGHT Shutdown is acknowledged with a brief acoustic signal. Automatic Shutdown The instrument is switched off automatically if the measured value remains unchanged for a long period of time (maximum measured value fluctuation of approximately 0.
Control Functions 4 Control Functions 4.1 Selecting Measuring Functions and Measuring Ranges Overview: Auto-Ranging and Manual Range Selection Function Display MAN 4.1.1 Automatic Range Selection The multimeter is equipped with auto-ranging for all measuring functions, except for temperature measurement, and diode and continuity testing. Auto-ranging is active as soon as the instrument is switched on.
Control Functions 4.1.3 Quick Measurements Measurements performed using a suitable fixed measuring range are executed more quickly than those which utilize automatic range selection. Quick measurement is made possible with the following two functions: • Manual measuring range selection, i.e. selection of the measuring range with the best resolution (see chapter 4.1.2) or • With the DATA function (see chapter 4.4).
Control Functions Ð Briefly press the ZERO | ESC key. The instrument acknowledges storage of the reference value with an acoustic signal, and the “ZERO ΔREL” or the “ΔREL” symbol appears at the LCD. The value measured at the moment the key is pressed serves as a reference value. Ð The reference value can be cleared by once again pressing the ZERO | ESC key. Notes Regarding Relative Measurement • Relative measurement effects the digital display only.
Control Functions 4.4 Measured Value Storage: DATA (auto-hold / compare) An individual measured value can be automatically “frozen” with the DATA function (auto-hold). This is useful, for example, when contacting the measuring points with the test probes requires your full attention.
Control Functions Example The voltage measuring range is set manually to 30 V. The first measured value is 5 V and is stored to memory because it is greater than 10% of the measuring range (= 3 V), and is thus reliable above the background noise level. As soon as the measured values drops to less than 10% of the measuring range, i.e. amounts to less than 3 V which corresponds to removal of the test probes from the measuring point, the instrument is ready to store a new value. 4.4.
Control Functions 4.5 Measurement Data Recording The cable multimeter is capable of recording measurement data using an adjustable sampling rate for long periods of time in the form of measurement series. Data are stored to a battery-backed memory module, and are retained even after the multimeter is switched off. The system acquires measured values relative to real-time. Stored measured values can subsequently be read out with the help of METRAwin 10 software.
Control Functions During Recording STORE is displayed underneath the analog display during memory mode operation, and memory occupancy can be monitored: Querying Memory Occupancy Memory occupancy can be queried during recording with the help of the “1nFo” menu (see also chapter 7.3). Memory occupancy range: 000.1% to 099.9%. StoP 000.3% MEASURE SETUP The following message appears as soon as memory is full: “100.0%”.

Interface Operation 8 Interface Operation The cable multimeter is equipped with an infrared interface for the transmission of measurement data to a PC. Measured data are optically transferred through the instrument housing by means of infrared light to an interface adapter (accessory), which is attached to the multimeter. The adapter’s USB interface allows for the establishment of a connection to the PC via an interface cable.
Interface Operation 8.2 Configuring Interface Parameters irStb – status of the infrared receiver in the stand-by mode There are two possible switching statuses for the infrared interface when the multimeter is switched off: ir on: IR appears at the display and the infrared interface is active, i.e. signals such as making commands can be received, and power is consumed even though the multimeter is switched off.
