The APPA A16 R and A16 HR clamp testers with silicon steel alloy (A16R) and Nickel-Steel alloy CTs (A16HR) are TRMS-reading instruments with a maximum current range to 1000 amps AC and DC, and with voltage ranges to 750 V AC (1000 V DC).
The APPA clamp testers feature a 4000 count, back-lit, large scale analogue bar graph and digital display. Measured parameters include frequency, resistance and continuity that are further enhanced by min/max and peak hold functions.
The APPA clamp testers have generous jaw dimensions permitting the clamping of conductors to 51 mm diameter. The clamp testers comply with Cat IV (600 V) and Cat III (1000 V) safety standards.
TRMS reading clamp testers are available from Power Parameters.
