FEATURES ● The RCB-3-1T is used to verify and proof any High Voltage    Insulation Testers. It can be utilized to calibrate all High Voltage    Insulation Testers very accurately Analogs or Digitals.● Some institutions and large industries requested their own calibrator    too, therefore, SEW started manufacturing the RCB for special    customers.     SPECIFICATIONS Resistance ranges (Ω) 1M. 10M. 100M. 1G. 10G. 100G. 1T Resistance tolerances ±1%(F) Tolerance  ± 25ppm/°C : 1MΩ. 2MΩ. 7MΩ. 10MΩ. 20MΩ. 30MΩ. 50MΩ. 100MΩ. 200MΩ. 500MΩ ± 100ppm/°C : 1GΩ. 2GΩ.  ± 200ppm/°C : 10GΩ. 20GΩ. 50GΩ. 100GΩ.  ± 400ppm/°C : 200GΩ. 500GΩ ± 1000ppm/°C : 1TΩ Max. working voltage DC 10kV Operating temperature -30°C~75°C Power coefficient Below 3W Connecting terminals Binding Post : Resistance circuit and guard Dimensions 430(L) × 324(W) × 127(D)mm Weight Approx. 4140g

FEATURES ● The 880 AT is a simplified Version of an appliance tester which use    low voltage and low current to perform it's checks.● Application Example   The appliance is plugged into the mini appliance checker, then the   probe make contact with the protective conductor.● Other appliance checking   Washing Machine Toaster Iron Dish Washer   Stove     SPECIFICATIONS       ELECTRICAL       Resistance Ranges    The L-E led will lit when the resistance between Line    to Earth is lower than 1MΩ ±5% .    The N-E led will lit when the resistance between Neutral to Earth is lower    than 1MΩ±5%  The EARTH BOND led will lit when the resistance between the EARTH to the Probe is higher than 10Ω±5% . Test Current    Line to Earth test current is 9uA maximum.    Neutral to Earth test current is 9uA maximum.    Earth to Probe test current is 2.3mA maximum. Maximum...
