The keypad is a set of three push buttons recessed along the upper right side of the
enclosure. It is not necessary to open the cover for use of the keypad. Access to the
menus is password restricted. Press any key for 3 seconds to enter the menus (see
below for details).
1.3 Password
The factory preset default password is 0017. The password can be changed.
IMPORTANT: RECORD PASSWORD IN A SECURE PLACE. If the
password is lost, the unit must be returned to
QEL to be reset.
1.4 Output Signals
Options are 4-20 mA or 2-10 VDC linear. Choose the option by moving the jumper
on JP1. On over range concentrations the signal can exceed the range slightly.
IMPORTANT: Voltage monitoring should be into a monitor with
at least 50,000 Ohms input impedance. Voltage
monitoring is not recommended over long
distances, as these signals are more susceptible
to induced noise than current signals
1.5 Meter Jacks
Test pads, accepting standard test probes are provided on the circuit card. These
are labeled SIGA, SIGB and COMMON.
To test the analog output signal, measure:
• SIGA to COMMON shorts to internal ground.
• SIGA to SIGB without interrupting signal to monitor.
To Test voltage signals measure:
• SIGB to COMMON.
