Note: When operated from a 24 VDC source, the maximum
allowable loop resistance is 480 ohms for Analog EZ
Modulevels. See Figure 9.
When operated from a 120 or 240 VAC source, the
Analog EZ current can only be monitored from the
meter terminals (M+ and M-) using a multimeter with
maximum sensitivity of 100 millivolts.
Caution: Instrument and conduit junction box covers must
be in place and tightly sealed at all times during
operation.
Note: Before connecting the power supply to the transmitter,
be sure that the voltage identification on the name-
plate matches the power supply. Do NOT attempt to
operate this unit at voltages other than as identified as
it will damage the unit.
