Battery Indication (Green Led); Overload Indication (Red Led); Maintenance; Warning - AEMC SL261 User Manual

AC/DC Current Oscilloscope Probe Model SL261
You may also use your oscilloscope to amplify the signal while using the
100mV/A probe range (which offers the best accuracy and least phase
shift).
Important: It is possible to change the range on the current probe
without removing the probe from the current carrying conductor,
but it is important to remember not to exceed the permissible
peak ratings of 1000mV peak or 2000mV peak to peak maximum.
The peak ratings by range are: 10A peak on the 100mV/A range,
100A peak on the 10mV/A range.

Battery Indication (Green LED)

The probe has a battery condition LED. To ensure proper readings with
your current probe, be sure that the green LED is lit during
measurement. If not, replace the 9V battery.
Peak Overload (OL) Indication (Red LED)
The SL261 offers an overload indicator. If the red LED illuminates during
measurement, this indicates that the peak value exceeds the instrument
response level and that the output is distorted. Switch the probe to a
higher range if possible.

Maintenance

Warning

• For maintenance use only specified replacement parts.
• Avoid electrical shock: do not attempt to perform any servicing unless
you are qualified to do so.
• Avoid electrical shock and/or damage to the instrument: do not get
water or other foreign agents into the electronic module.
• Also see warning on page 2.

Battery Replacement

When the probe is turned on, the green battery indication LED should
light up. If not, replace the 9V battery (see figure 1). To replace the
battery, disconnect the probe from the circuit and the oscilloscope. Turn
the probe "OFF". Unscrew the battery compartment screw and pull out
the battery compartment cover. Replace the battery and put the cover
back on. Do not replace the battery while probe is in use.
