Detail Hioki Meter Relay 2103 :

• Ultra semsitive 1 µA, 10 mV DC movement
• Includes a display lamp to illuminate movement at a glace
• Relay action delays circuit closure upon power on
• Both power circuitry and relay bulit-in
  *H-type : Lamp lights up and output relay contact operates at defclection of needle to the right of the setting needle
  *L-type : Lamp lights up and output relay contact operates at defclection of needle to the left of the setting needle
  *HL-type : Provides functionality of both H- and L-type models
