IM CA150E
IM Normal SettingSets and queries the mask of status byte
○ ○ Command = IMm<Delimiter> → Answer = IMm <Delimiter>
Command = IM?<Delimiter>
→ Return = IMm <Delimiter>
Performs detection or sets mask for each bit of status byte.
If IM0 is set, all information bits are masked.
If IM63 is set, the current operating conditions are reflected for all
information bits.
(No mask)
Parameter m = 0 to 63 (Decimal number)
1: Detects bit 0 (Measurement Ends)
2: Detects bit 1 (Output Change Ends)
4: Detects bit 2 (Syntax Error)
8: Detects bit 3 (Overrange)
16: Detects bit 4 (24 V Loop Output Error)
32: Detects bit 5 (Error During Output)
(Bits 6 and 7 of the status byte are fixed bits.)
default Value of m = 63 (No Mask)
MF Normal SettingSets and queries the measurement function
○ ×Command = MFm<Delimiter> → Answer = MFm <Delimiter>
Command = MF?<Delimiter>
→ Return = MFm <Delimiter>
Parameter
m=0: DCV/1: DCA/2: &ohm&/3: TC/4: RTD/5: Freq
MO Normal SettingTurns on/turns off and queries the measurement value indication
○ ×Command = MOm<Delimiter> → Answer = MOm <Delimiter>
Command = MO?<Delimiter>
→ Return = MOm <Delimiter>
Parameter m=0: Turn off/1: turn on
MR Normal SettingSets and queries the measurement range
○ ○ Command = MRm<Delimiter> → Answer = MRm <Delimiter>
Command = MR?<Delimiter>
→ Return = MRm <Delimiter>
Parameter
[DCV] m = 0: 500 mV/1: 5 V/2: 35 V
[DCA] m = 0: 20 mA DC/1: 100 mA DC
[Ω] m = 0: 500 Ω/1: 5 kΩ/2: 50 kΩ
[TC] m = 0: K/1: E/2: J/3: T/4: R/5: B/6: S/7: N/8: L/9: U
[RTD] m = 0: PT100/1: JPT100
[Freq] m = 0: 100 Hz/1: 1000 Hz/2: 10 kHz/3: CPM/4: CPH
ND Normal SettingSets and queries the n and m values for divided output (n/m)
○ ○ Command = NDnm<Delimiter> → Answer = NDnm <Delimiter>
Command = ND?<Delimiter>
→ Return = NDnm <Delimiter>
Parameter
n = n value (2 digits from 00 to 19, n ≤ m)
m = m value (2 digits from 01 to 19, n ≤ m)
default Value of n = 01 and m = 01
