MAX mode testing
First, with instrument in SEARCH mode,
select appropriate sensitivity level.
Place probe at test point and press MAX si-
multaneously . Leave probe in position.
The instrument will now measure for 10
sec. (MAX lamp is blinking) and then
indicate the signal strength (MAX mode
lamp stays on).
Note the reading and proceed to next test
point. For a new test, place probe at next
point and press MAX simultaneously.
To get comparable results it is very im-
portant that you place the probe at the test
point in exactly the same manner.
The MAX mode is primarily intended for
Hand Probe H21 (under manhole covers)
and for Surface Probe 8612 (on manhole
covers and hard toppings).
If the selected sensitivity is inappropriate,
you must press SEARCH before changing
sensitivity.
Press MAX again to proceed.
Error codes
If an error is detected, the instrument will
give off a pulsating acoustic alarm signal
and the ON lamp will blink red.
The type of error is indicated by the
LEDs:
LED 1 = Sensor temperature low.
LED 2 = Sensor temperature high.
LED 3 = Sensor voltage low.
LED 4 = Sensor voltage high.
LED 8 = Battery voltage < 5.0 V.
LED 1 and 4 simultaneously, most likely
means that either the cable or the probe is
not connected.
A single LED 1, 2, 3 or 4 most likely
means that either the cable or the sensor
is broken.
LED 8 means battery needs to be char-
ged.
Charging
The instrument will switch on when char-
ging cable is connected. Charging is fully
automatic and ON lamp will blink until
battery is fully charged (12 h).
Charging voltage is 9 —15 VDC. Current
is limited to 1.5 A maximum.
Charging from car battery is possible.
1 h charging gives 6 h of operation.
5 minutes gives approx. 20 minutes.
For prolonged battery life – charge often
and fully!
