4.2 Introduction to Main Interface
Figure 2-1
Functions:
1. Zone on/off;
2. Zone status display: four colors to indicate four different status– on, off, light load and overload;
3. Load change rate display: R% = original load/actual load*100% (Original load value: load of first-time
calibration)
Note: the error of scheduled detection, all zone detection and single zone detection for used zone is within 20%;
the error of real-time detection for unused zone is within 10%. Therefore, if the detection data changes when
performing scheduled detection, all zone detection and single zone detection, please manually turn off the zone, so
as to further confirm the detection result through real-time detection. Each time the zone is turned off for real-time
detection, wait for 30 seconds to stabilize the data before reading the test data.

(1) Zone function description
All zone detection: press this button to detect all 20 zones.
Single zone detection: press this button and choose a zone to detect. Note: no other operation could be
done at the same time.
Single zone calibration: press this button and choose a zone to calibrate (only zones that are
successfully connected and load rate is not 100% could be calibrated individually). Note: no other
operation could be done at the same time.
All zone on: press this button to turn on all zones.
Fault Ack: this button will turn red and give alarm when there is light load or overload in some zones.
Press it to stop giving alarm.

Note: If some zones are not used, please insert a 4P/5.08MM interface with 1.5K/0.25W resistors into the unused
output as shown in Figure 2-3 (this interface with resistor is not allowed to connect the amplifier output), so that
all the zones will be displayed normally.

1. Detection interval: no more than 24 hours and no less than 60 seconds. Note: When performing scheduled
detection, selecting the corresponding channel under the status display bar is needed before it takes effect.
2. Threshold of all zones: alarm threshold of impedance change for all zones (20~99% is light load, above 100%
is overload, 100% is normal). You can also set the impedance change threshold for each partition separately under
the Status display bar. Tap the number in the light load or overload and press ENTER when the settings are
complete to save the settings. Note: threshold set for all zones will override threshold for each zone.
3. Backlight time: click “ ”, five options– 1 minute, 10 minutes, 30 minutes, 60 minutes, always on.
4. Language: click “ ” to change language.
5. Tap sound: to set tap sound.
6. Alarm sound: to set whether to give out alarm sound when fault occurs in zones.
7. All zone calibration: open this button to calibrate all zones. It will close automatically.
Note: all zone calibration is needed at first time use or after repair and maintenance.
