Dip Switch (Factory defaults to OFF-Down)
1.
Auto Power Off:
10 minutes without key
operation, automatic shutdown.
2.
Manual Cold End:
Manually set the cold end
value when measuring thermocouples.
3.
Passive Output:
outputs a passive current
signal for analog transmitters.
4.
Low Load Mode:
When the passive current is
input, calibrator supplies 16 V to the transmitter
to reduce power consumption and prolong the
use time.
LCD Display
a: Measurement:
4 digits with unit
b: Output signal value:
4 digits with unit
c: Signal and cold end mode:
20 mV/100 mV/
4-20 mA/K/E/J/T/R/B/S/N
RJA: automatic cold junction compensation
M: manual set cold junction compensation
d: Programming function:
n/m to split the output,
Output value = (Main Set Value)*(n/m)
Sweep:
Linear output, Linear output signal
Step:
Stepping output
Time:
Output time for each step, 0-999s can be set.
Count:
Output cycles, 0-999 times can be set,
0 is infinite
e: Unit:
mA/mV/°C
f: Range and change function:
RL: Show the lower range limit
RH: Show the high range limit
SL: Show the minimum signal
SH: Show the maximum signal
g: Battery:
Icon flashes when charging. Icon will stop
flashing when fully charged.
