Mounting the instrument in a rack
How to secure the rack-mount brackets
• Support the instrument by installing commercially-available support angles in the rack because
the instrument is heavy.
• Leave 20 mm or more from the bottom side and the sides that have the vents (upper, right, left,
and bottom sides).
• If you need the screws (M4 × 8 mm), please contact your authorized Hioki distributor or
reseller.
