Simpson 260 Series - AC High Voltage Probe Details; Amp-Clamp Model 150-2 Operation

Introduction
Accuracy: Probe Resistance +2%.
The DC high voltage test probes are available at local electronic
parts distributor.
Accessory AC High Voltage Probe
The 10,000 volts AC accessory probe is similar to the high voltage
DC probes with the following exceptions: The AC high voltage
probe is designed to extend the 260-7P AC voltage range. The
probe can be used with the Simpson 260-7P 10-volt AC range.
NOTE: Instructions are furnished with each high volt-
age probe.
AMP-CLAMP MODEL 150-2
The Simpson Amp-Clamp Model 150-2 allows AC current meas-
urements without breaking the circuit under test. The Amp-Clamp
works in effect as a transformer containing a split core for accom-
modating the conductor which carries the current being measured.
The current carrying conductor becomes the transformer primary
and a coil in the Amp-Clamp serves as the secondary winding.
The Amp-Clamp output voltage is proportional to the current
measured and can be applied to the 260-7P as an AC voltage.
The Amp-Clamp has a range selector with 6 positions. Any of the
following current ranges can be used with the 260-7P:
5, 10, 25, 50, 100 or 250 amperes.
NOTE: Instructions are furnished with each Amp-Clamp.
