Electronics Unit (cont.)
1-2
The front panel of the electronics unit contains a 2-line x 20 character
Liquid Crystal Display (LCD) to show measurements, a 4 x 4 matrix
keypad for entering data and operating the MMS-3, and four function
keys.
The MMS-3 is also available with an optional rechargeable battery
pack that makes it ideal for survey applications. The user can move
the MMS-3 from location to location to take spot samples and store
measurements. When fully charged, the battery pack provides eight
hours of continuous operation.
The BASEEFA-approved electronics unit is available in rack mount,
portable bench mount, and panel mount versions. The electronics unit
is also available in NEMA-4X weatherproof and NEMA-7 explosion-
proof housings, but these packages are not BASEEFA approved.
IMPORTANT: Only the MMS-3's that have serial numbers 2001 and
above are intrinsically safe.
