Standard test conditions:
Ambient temperature/humidity ranges: 23 ±5:/45-75% RH Position of use: Horizontal (5° max. of angle of inclination)
External magnetic fields: None
Battery voltage: Within effective voltage range
(The pointer must stay within the range indicated by the BAT symbol when the battery check is performed.)
Tolerances under the above-mentioned conditions:
Resistance measurement: First effective measuring range = ±5% of reading Second effective measuring range = ±10% of reading
Infinite and zero scale values: 0.7% max. of scale length AC voltage: ±10% of maximum scale value
No-load voltage: 130% max. of rated voltage
Rated measuring current: 1 mA (0 to 20%) when in first effective measuring range
Short-circuit current: 12 mA max.
General Specifications
Scale length: Approx. 86 mm (outer scale)
Discharge function: The tester automatically begins discharge when you turn off the MEAS switch. The pointer swings if there is any residual voltage in the circuit under test. You can make sure discharge is complete by checking that the pointer swings back to the infinite (∞) scale value. Under this condition, the tester is ready to enter voltage measurement mode.
AC voltage measurement: AC voltage measurement is possible wherever the rotary switch is positioned.
Dimensions (main unit): Approx. 120 (W) 110 (H) 60 (D) (mm)
Weight: Approx. 500 g (including batteries)
Batteries: Six AA (R6P) batteries
Accessories: See the list of accessories on the backside of this bulletin for information on accessories.
