6. Operation

The output voltage range is ±2.3 V. The transfer factor depends on the set

measuring range. For example a measuring range of 2000 mT results in a

transfer factor of 1 V/T.

6.3.1.17 Probe Connector

The AS-active-probes will be connected to this connector. Thereby the

probes should also be screwed. To connect / disconnect the probe the

Teslameter FM 302 should be switched off.

Plugging in the AS-UAP-probe care should be taken not to mechanically

stress the control elements at the probe connector.

If no AS-probe is connected to the Teslameter FM 302 the display shows

"no probe"" (see also section 6.3.1.6 Display).

The Teslameter FM 302 offers a USB interface compatible to USB 1.1 and

USB 2.0.

To this port a USB cord with type B plug can be connected to connect the

Teslameter FM 302 with a PC. A suited cable is included in delivery (see

also section 5.3 Items Supplied).

Via the USB interface the Teslameter FM 302 may be controlled and the

measured values read out (see also section 6.3.3 USB Interface). . Also the

device can be powered via the USB connection so the battery is preserved

and there is no need for a power adapter.

If the instrument is powered externally, it is supplied with 9 V through this

connector. (see section 6.3.2.4 Power Adapter Operation). The inner port is

the negative supply voltage.

The battery compartment houses the 9 V battery or a 9 V accumulator (see

section 8.2 Checking Battery and 8.3 Maintaining Accumulators).

To open the battery compartment the cap at the rear of the device is drawn

away.
