CONTENTS 1. APPLICATION Application The field strength meter FSM- 2, in conjunction with the tangential field probe, digitally registers and displays magnetic field strengths (H) in the range of ± 400 A/ Safety information cm, enabling you to measure direct magnetic fields as well as alternating magnetic Identifying parts fields.
2. IDENTIFYING PARTS Socket for Socket for connecting to power supply connecting the tangential Compartment for RS232 data field probe battery pack (9V) output socket LCD display with selectable backlight ON/OFF button (see below) Cover for closing the bottom of the MODE or RMS/PEAK button device (see (see below)
Power supply socket 2.1 SUPPLY The FSM-2 meter is suitable for operation with an external power supply (12 V = / The FSM-2 field strength meter is supplied with: 125 mA) in combination with a 9V battery (NiCd or NiMH). The battery is permanently fed with a small current (maintenance charge).
3. OPERATION PEAK The PEAK function displays the highest values of the positive or negative peak values for the actual magnetic field without a sign. This allows a quick assessment 3.1 SWITCHING ON of the maximum field strength without considering the polarity. A short press on the ON/OFF key will turn the device on.
3.4 TANGENTIAL FIELD PROBE Operational mode selection With the FSM-2 in normal operating mode (not in setup mode), press the MODE or The tangential field probe can be permanently connected to the FSM-2 via the RMS/PEAK button (depending on the model) to cycle through the following display socket on top of the unit.
FOR MAGNAFLUX MEASURING INSTRUMENTS NOTE: if you order a reference standard once you have started using the FSM-2, you will need to send the entire unit to Magnaflux GmbH for calibration. 3.5.1 Tangential field probe FSM-2 with reference standard (optional) The display accuracy of the FSM-2 should be periodically checked using a refer- ence standard.
